Yea once my BMW 335i hit 140,000 km, I started hearing whistle sounds and I had to replace the twin turbos. BMW covered the cost of the new twin turbos, but I had to pay for the labor. Then they found more things that needed to be fixed, so ended up paying $2000 CAD for labor.
I also like Honda S2000. I've never driven it, but a lot of people tell me it's real fun.
I also like 1997 - 2004 Corvette C5, LS 5.7L engine real nice, very quick, and the sound is amazing. I've drove my friend's car and it's a BEAST at the drag strip. He added turbo and ran 10.5 - 11 seconds on quarter mile with a C5. z06 is also a BEAST.
he, what to expect - turbo change .. fuck. but the problem comes that when somebody buys 2nd hand.
S2000's nice and good value too.
Corvette I wouldnt bet for three reasons - not possible to use that as daily driver and 5.7 is too much taxes to pay as well I would be seriously mad about he shit quality and no redeeming features (i don't talk about excessive stuff)
both of these are not comparable with E92 however.
