I really don't know too much about the 335i just test drive it once. Off the records, BMW lost this customer already. You can see I sold my E90 330i in 11 months and you can understand why.
My feel about the 335i just after a short test ride can summarize below
1. If you got the 2 doors, Very good looking car.
2. Very fast, faster then the E90 330i without mod.
3. lots of room to mod it up to 400 Bhp since its a turbo engine.
4. The turbo engine is also the one I don't like. Its a modify E46 330 engine not like the 330i. A band new designed engine and the E90 330i engine is good.
5. The build looks good on the 335ci but don't know how long it least. My 330i is good for 2 months and everythings goes wrong. (Electronic wise not engine or gear box.)
Since I have a Porsche 997s as a fast car. This time I go for a more comfort ride car.
Actually, 997s has a lots of problems as well but I just like Porsche and that is why I keep it.
