Congrats.
Make SURE you get a 335 that has the oil cooler built in. If you've read the Roundel and other Car Magazine reviews, it apparently doesnt take much to get the oil temps up to the 300 degree range, which shuts down the engine into temporary limp mode.
Not to hate..but personally? I'd shy away from BMW first model year brand new engines. History has shown that BMW usually has significant issues whenever they develop a brand new engine. Whether its the sulfur issue with the mid 90's V8 engines, the major bearing issues (oil supply) wth the E46 M3 engine when it was introduced (many engines were replaced under warranty), the weak valve retainer springs on the 1995 E36 M3 engine, or the apparent turbo heating issues with the new 335. BMW always has trouble when they first release new engine designs. And this being the first gas engine turbo BMW has released in the US in over...what 40 years? I'd be a bit nervous with it.
That being said, my second car is a 1999 E36 M3 Convertible, and it's a great car.
Good luck.
