Saab. Very good, solidly built cars and again very reliable from what I've experienced. Might be heading into Volvo territory in terms of style (Sorry Kyle ) but this probably means even Greg would be hard pushed to break it. Not sure on the availability of parts out there, obviously you're better placed to work that out.
It's better than a Hyundai... Brad, I don't think any of the cars on your list are that great... If the VR6 has been very well maintained and doesn't have any broken bits off the bat, then sure, go for it. If it hasn't, well, it's going to be like V8 Turbo all over again, but with a "bit" more power.
About the Saab... Those are getting older, and parts are getting to be more of a pain in the ass. I work on saabs a lot at my work, and they need constant maintenence... Not cheap either.
The Suzuki, cool cars, but I doubt it's too easy to get parts for the quick ones still, or maybe it's not bad? I don't know.
Hyundai may not be the coolest by any step of the imagination, but it'll definitely be the quietest, most reliable, and most comfortable... And cheapest in the long run. Try to of course find one that was taken care of...
That being said:
I put the car on the dyno Tuesday this past week... Clamped the kickdown cable in place right before the kickdown switch comes into effect, and was able to start my dyno pulls from ~2500rpm instead of the ~3500rpm that I was doing them from in Jan. of '06. I managed to pick up 4whp(up to 99whp and 127wlb-ft) with a less aggressive camshaft, while having much more area under the curves as well. The changes have been a K&N air filter in the modified airbox(had a stock paper filter in there before), a crank scraper, one heat range colder spark plugs, 3 degrees more advanced ignition timing, and who knows what else. I was even having ignition troubles up top on the dyno that I've since fixed...
It should be over the 100 mark now. Yesterday I tossed in an adjustable cam gear and advanced it two degrees to pick up a smidge more power off the line, and the decrease in pull up top isn't noticeable now that my ignition problem is sorted out. I want to go back to the dyno now! But that costs money. Of which I shouldn't be acting like I have... *sigh*
:-D
