I've owned two Volkswagens previous to my current Celica, and while I still think they are great cars to own and drive on a daily basis, there are a lot of extra costs involved that a lot of people don't consider.
- Volkswagens are notorious for being unreliable. Generally, it is true for all models, engines, transmissions, etc.
- Worse yet, Volkswagens are very expensive to insure. Why? Parts, man.
- Replacement parts for the Volkswagen? Expensive. You think a BMW or Mercedes is bad? Volkswagen is just as much, if not moreso.
The good news is that middle-aged Volkswagens are easy to work on, and can be a good place to learn a thing or two about keeping your own car together. But, you're rolling the dice on reliability every time. Here's what I'd look at if you're dead-set on a VW...
1996-1999 MKIII Volkswagen Golf/Jetta (2.0L I4): The later versions of the MKIII were vastly more reliable than the original models. I had a '96 Wolfsburg, modestly equipped, it was a pretty nice place to be. It was quiet, decently fun to drive, and managed 32 MPG without working too hard. You could do a decent amount of work yourself, parts are fairly easy to come by, and you can pick up a fairly decent one for well-under $5k.
1996-1999 MKIII Volkswagen Jetta GLX VR6: If you want a "fast but cheap" Volkswagen, the GLX VR6 is the way to go. You get the MKIII stuff from above, plus a 176 BHP VR6. They're fairly reliable (for a VW), and are decently quick (as fast as a BMW E36 of the same era), and can be found for pretty reasonable prices. If you want a quicker car to learn with, this would be a decent place to start.
1999.5-2002 MKIV Volkswagen Golf/Jetta/New Beetle: Avoid, avoid, avoid, avoid, AVOID at all costs. All engines, all transmissions. No. Don't. Reliability is terrible across the board.
2003-2005 MKIV VW Golf/Jetta: There are a lot of variants at play with these models. Reliability is improved, but it isn't anything to shake a stick at. Extremely expensive to insure and repair, even more difficult to work on. The 2.0L was a carry-over from the MKIII, the 1.8T received a power boost in 2003, and the VR6 soldiered on with its 203 BHP the entire time. My friend's VR6 GTI is okay to drive, but it is more of a luxury car than a sport compact.
If it were my money, and I was dead-set on getting another Volkswagen, I'd be looking at three separate models:
- VW Corrado SLC: Avoid the ladder-charged G60, go straight for the VR6. Thing is, these are collector items these days. They should be treated as such.
- MKIV VW Jetta GLI 1.8T: I like the look, the comfort, and performance of the car. Nothing to shake a stick at, more of an "adult" car than anything else
- MKII VW Jetta GLI: I want a 16V Jetta for one reason: 16V 1.8L I4.
Generally, avoid collector models. That includes the R32 (MKIV and MKV), 337, or any of the Anniversary or Fahrenheit models. Collectors keep the prices up, and it just isn't worth the extra money. Stick to the value packages, the Wolfsburg Jettas are a "best of both worlds" trim that often included the better options, but wasn't enough to consider itself a luxury package.
Still, if you're spending $15K?
You're better off getting a Mazda 3. Drives like a German car, has the Japanese reliability, and the prices aren't half bad. Just stick to '09 and older.
Or if you really want a reliable sleeper?
Get yourself a Toyota Camry or Solara SE with the V6. Not only will it slide under the radar of just about everything, it'll blow the doors off most of the "fast" Volkswagens without breaking a sweat. That, and you can get well-kept examples for under $10k without working too hard.
