your arm and your leg

 

Ya i don't know about superchargers.. those kill gas milage. I've heard they might go back to twin turbos.. that way you get the fuel economy and power up top. As Far as Audis Reliability, Its no Honda.. you might have to change a few other thing besides Oil.. Oh ya and the S5 is already known for burning oil.. I'd wait for an RS5 though..

 

Well the supercharged V6 will give you more fuel efficiency compared to a V8.

 

 

Since the S5 is around $52K base, I will say $63K, when all is said & done with options it will be around low $70K's. A fixed up S5 right now goes for about $60K.

 

Given the current price gaps with the S4 and RS4, I would venture to guess the RS5, if made and sold here in the US, will cost $80k plus or minus...

 

I drove one for the audi challenge on the cali speedway road course. It definitely has power, but damn does that thing roll. Tracked the S2k on the same course on Saturday, and had worlds more confidence.

But the S5 is beautiful, and I've always been partial to Audi interiors. If you never track your S2k anyway, I say go for it if you have that kind of money to blow.
