Audi *use* to have a bi turbo in the S4. No longer. Now it's a v8. Too many people complained about the maintanence.
All recent VW/Audis with a 2.0T (single turbo), which isn't bad and it's pretty tunable by several tuners.
BMW 335i is a bi-turbo. Reliability is still to be proven, because this is a first generation engine Drove the car, like it (near as fast as the outcoming e46 m3) Unfortunately, most people who get a 335 have no clue about the car itself, so I don't like the stigma. Plus bmw likes to nickel and dime you (they probably charge for the air you breathe inside the cabin). Also, I don't like how you can't do basic maintanence (you can't check the oil easily). Also, driving without a spare bothers me (3 series all use run-flats and don't come with spares.)
Other than that, I'm not aware of any other cars these days that are bi-turboed, just single turbo, though turbo lag really isn't an issue these days unless you run a modified larger turbo.
Other choices I personally like as a hoodlem car:
WRX STi (if you don't mind the way it looks)
Mitsubishi EVO (if you don't mind the way it looks)
If I had to get something right now, I'd probably get an Audi A3 or the 08 TT with the 2.0T. Not too pricy, and decent performance, plus very tunable by several VAG tuners. But, personally, I'm waiting for the A5/S5/RS5, which will be about the right time since my cars run on a 10year lifecycle. Only issue is I believe both are only available FWD, not AWD (could be wrong though).
