STI was a mean machine. It towed the bikes to the track. Fast in snow, very fast in summer. A young kid offered me good money for it. I was forced to sell it. Plus I am a German car guy at heart.
The new S6 has a twin turbo V8, that is at roughly 400hp. I've been driving that for the past few weeks. LOTS of power.
That car weights like 2lbs. Hah, but no, we don't have one at the facility right now. Supposedly we will be getting a TTS at some point next year.
I've put 99000 miles on my '08 A5 with the v6 and a manual trans. It's a rolling piece if shit... Worst car ever made... It will make your penis smaller, and your hair fall out. Your bikes will all catch on fire, your dogs will die of aids, and all your shrubberies will wither and die. I do average 30 miles to the gallon though. So that's kinda cool. I'd recommend the 2 liter Turbo though. Huge aftermarket.
Yahoo has some story about the cars with the best resale value. The Q7 and A5 are on there. Edit, here's the story: http://autos.yahoo.com/news/best-resale-value-cars.html?page=1
This post makes me nervous! Still having trouble find one in my budget range. I made an offer on a 2006 s4 w/ 45,000 miles. $22,000. Owner declined and said $23,000. I'll let him ferment a bit.
