 The 335i offers an intoxicating engine and a very good chassis with near perfect balance.  Sadly, the engine's got a common problem burning through fuel pumps, the chassis is upset easily by the poorly conceived RFTs and the car's balanced but 400 lbs too heavy.   I picked up a CPO 335i ZSP as a family car that could offer some space that my Cooper S lacked.  In that regard it does fine.  No, I'm not getting 30 MPG now (more like 22), but I do have room for the baby in the back and a good sized trunk for family outings.  Perfect, if not for: weight (unavoidable), RFTs (replaceable) and engine/turbo malfunctions (I've had nearly all turbo-related parts replaced over 16 days at the dealer).
