Re: Volvos, VW\'s, Saab\'s, Audi\'s and other EUROPEAN cars...
Brock, I'm a big fan of the TDIs. VW's diesels have a pretty solid reputation for going 250-300K miles. The new ones are quiet and barely smoke. I've stood next to them and only the very faint difference in odor was what tipped me off.
The high compression ratio used in diesels offer a couple of advantages.
Higher volumetric efficiency, which contributes to the high MPG ratings they have.
The compression is also responsible for the torque that diesels have. With torque, you can gear a transmission with pretty long legs and performance won't suffer, and with a nice low top gear, your highway mileage is around 70-100% better than a gasoline engine in the same car. Grab a gear, let the motor pull through a wide bottom end and midrange, shift, and repeat.
Here's a couple of websites you can check out for more info on the TDI from real owners, not paid magazine hacks.
http://www.vwvortex.com (They have a similar discussion board there.)
http://www.tdiclub.com/ (They've just revamped their forums, but all the old messages have been archived for reference if you need them.)

Frankly, I'd
love to have a TDI. I know several people who have them, and they've proven to be very good cars. There are regular quibbles that seem inherent with different models of cars. VW has had ongoing problems for years with their power window regulators. They had a bad run of A/C compressors in some of their `95-`97 models.
Unfortunately, I wouldn't be able to leave mine alone. I'd have to put on an aftermarket exhaust, springs and shocks, and chip the brain. You can add a performance chip to the control computer on TDIs. While there's no "spark curve" for the chip to tweak, there is a fuel, turbo pressure and wastegate maps.
The Wetterauer (sp?) and Upsolute chips increase the hp from 90 to around 120, and the torque from 150 ft/lbs into the 200-220 range. More tweaking and upgraded injectors will get around 150 hp and nearly 300 ft/lbs.
I'd be out of control. I have enough problems with leaving my current 16V stock. A TDI would be like a blank canvas to me...
