In 1973, I went to work as a fledgling mechanic in a nearby VW dealer, Hassan Motors, in Norwood Ohio. I had just got back from the war a year before, and after goofing off for a year was finally ready to start some sort of career. Before I was drafted, I went to a local community college to learn about computers, but everything I had learned had disappeared by the time I got back, and it was time to start over. I should have found some way to get back into computers, as even then it was obvious that it was going to be big. However, my love for mechanical objects (cars) was overwhelming, so off to work I went.

Computers were shortly to take over the car business, and into my first year on learning to repair cars, I came face to face with the VW Diagnostic Computer, a machine introduced to dealers in 1973 as mostly a marketing gimmick, but did show the way forward.

The computer took up a whole bay, and plugged into the diagnostic socket in the engine bay. It couldn’t really do much, mostly would tell you how much the alternator was charging, but people got the readout and really thought they had something. VW had just released their electronic fuel injection on the squareback models just a few years prior. These were simple things, and if you took the control units apart, could practically build them yourself. They weren’t very sophisticated, and could run better, but most cars then were having trouble with the new emission laws, and they could all run better. The saying at the time was, “We can make them run clean, or we can make them run good, which do you want?” We even had a serial Luddite in Cincinnati that was killing these cars. In a VW squareback, the control unit sat close inside the left rear fender, next to the engine’s air vent. Someone who knew where the control unit was was driving something similar to an icepick through the fender and into the control unit. I don’t remember how many of these cars we fixed, but it was a significant number.

In the end, the VW Diagnostic Computer was deemed irrevelant, and the machine was sold to the dealer for one dollar, and they could dispose of it any way they wanted. I kept a few boards out of it for years, hanging them on my garage wall. Kind of a picture into the future. Every car has a diagnostic socket today, with the laptop taking the place of the behemoth of the early seventies…

Cars are better than they’ve ever been. They can go thousands of miles with little or no maintenance and are marvels of engineering science. The littlest economy car is safer to crash than the biggest 10 year old sedan. Gas mileage keeps going up and pollution levels keep going down. What’s not to like?

Cars are designed to be easy to manufacture. Nowhere in the manual does it say anything about ease of repair. The first time you want to remove a hose clamp, you notice that it was obviously installed when the motor was out of the car. You can only hope to get a tool on it. Then you want to remove an electrical connector. Good Luck. Every one is double and triple locked, and each one is unique. By the time you figure out how it comes off, you’ve already broken it because, after all, it is only plastic. And getting a new one from a parts guy is difficult also, as there are thousands of them on a car, and he’ll be searching forever to get the right one, which he won’t have, and it you order it, it is guaranteed to be the wrong one when it comes in.

Parts are subassemblies. To decrease the burden of stocking thousands of parts, subassemblies have become popular. To buy a fuel pump for a pre-millenium car, you bought a fuel pump. Now you get a giant box that is almost as big as the fuel tank, with numerous plastic hoses, valves, sensors and what not. Buried deep in all this mess is the tiny fuel pump, now just a miniature version of it’s previous self. Granted things are more complex now, but still….

Cars are getting lighter, but tires are getting heavier. Tires have been growing in size every year, till now it’s almost common to see 18 and 19 inch tires on cars. The aluminum rims used to be lighter, but now are so big that you need to be the Incredible Hulk to change one. When I started working on cars, tires were usually 6.00 by 15 inch, and you didn’t even need a power machine to put a new tire on a rim. And those rims were steel also, but still lighter by a long way than modern tires.

Cars are incredibly sophisticated. The only modern machines that are more complex than cars are jet fighters. Mechanics are starting to need college educations to understand them. People that work on their own cars are increasingly fighting an uphill battle, not the least of which is access to information. Car Manufacturers consider any and all information that isn’t in the owner’s manual to be a state secret. Even the amount of money it takes for special tools and electronic scan tools can bankrupt a dealer, ,much less an individual that tries to figure out his own car.

I’m at a loss to think what you’ll be giving your kid to drive when he’s 16, a few years from now. Everyone can’t afford to put them in something brand new, and almost every 10 year old car will be as sophisticated as the space shuttle, will cost thousands of dollars to fix when it needs it, and you won’t be able to do it yourself to save a few bucks, even it you are handy. Cars from the 60’s were a lot easier to understand, and could be fixed by the average Joe. Older MG’s and Chevy’s have quite a following as parts are cheap and available, and the cars are simple to understand and repair. Car makers need to meet us in the middle somewhere.

In 1994 GM had 1/2 interest in Saab, and soon owned the whole automotive division. They pushed the car upscale and eventually killed it, and now the corpse has now been hacked up, dismembered and parted out to a Swedish/Chinese/Japanese consortium with dreams of making an electric car. I’m not really sure, and I’m believe they aren’t sure either, but they might not get the name as Saab in Sweden is still a military-industrial complex and don’t want to dilute their good name.

As far as US Saab dealers go, they have gone out of business, or are in the process of reinventing themselves. For all the hoopla from Saab owners how they are going to bring the car back by demonstrations and such, they haven’t really supported the dealer network much, and have stayed away as long as they possibly could, not really wanting to spend any money on a dead horse. Parts have been really tough to get, and keys for Saab Sports Sedams have become a hot black market item. A late model 9-3 involved in a small fender bender was recently totaled because there were no front fenders in the country, and no prospects of any soon.

The shops generally remain empty. Some cars have to come back since they have bizarre German GM electrical systems, and no one else seems able to understand them, much less fix them. Mechanics have been pretty creative repairing parts instead of replacing them, something done routinely in the thirties, but not even done today. Other makes of cars are drifting in, but bringing in customers that are already going somewhere else is tough. Getting a different franchise is out of the question also. All the car makers have recently thinned out their dealer networks, and aren’t interested in any more.

As far as myself, I’m getting close to retirement anyway. So this whole thing doesn’t affect me as much as it could. But I’ve been working on Saabs since 1985, and will miss them, although they will still show up as orphaned cars at the shows, much like Edsels, Hudsons and the millions of other makes that have been abandoned.

I have been spoiled by Saab. They got good gas mileage, better than average performance, looked good and if you got them into the air on a bump in the road, they could land on all fours and still be in control. I tried that with an Oldsmobile once and almost got killed.

Update Nov 13, 2012
Well, life goes on. The cars are trickling back, I’m still working here, and we have 3 mechanics working. Wages for flat rate guys are still depressed, and the mechanics are struggling to pay their bills, but they have work. We’re not over the hump yet, but getting there.

Swedish David Blumbeg wrote a song and put together a mashup of Saab commercials in support of finding a new buyer for Saab. Other enthusiasts have also responded with the website IwontbuyfromGM, looking to lean on the General. For more Saab news check out Saabs United.

Back here at our Saab dealership, certain cars have taken up what appears to be permanent residency. These cars are waiting for parts that are on serious backorder. I originally thought it was due to the economic slowdown where factories are shuttered till things began again, and that was the problem in the beginning. But now it’s because GM won’t or can’t pay it’s bills from being in bankruptcy court.

We went without fuel pumps for a couple of months.. now I have a car waiting on a switch for the brake vacuum pump, which is kind of a necessary part, for a month now. The supplier in Germany is still making the part, but not giving it up till GM pays for it. And GM isn’t paying for it. And Saab and GM is still paying for rental cars for people still in warranty. (You would think it would be cheaper to just pay for the part.) If you’re out of warranty, your on your own.

However the parts are out there. Sometimes the aftermarket parts are made by the same company, in the same packaging as the original factory supplied part. And they are a lot cheaper as they don’t have the franchise supported markup that dealers are famous for. However, in our case, we are forbidden by franchise rules to use these parts or any other parts not supplied by GM.

Granted, this is a unique situation we are living through, and I will be glad when things get back to normal. But that may be wishful thinking, as normal is probably dead and gone.
