I thought audi s4 had decent reliability (not japanese caliber) but at least as good as bmw....

 

I think its only fair to list new cars. Comparing a new G35 alternative to a used car is an apples to oranges comparison.

So, here's my picks:

2005 Pontiac GTO
2005 Mustang GT convertible loaded or a 2005 Saleen Mustang
2005 MazdaSpeed 6
2005 BMW 330i
2005 Saab 9-3 Aero
2005 Volvo S60-R
2005 Jaguar X-type
2005 Acura TL

Lots of nice choices.
