my friend had one in the 90's, purchased in TX, and brought south. It was a good car. It's not a 325i, doesn't have that dynamic performance, and is a different style to a 318i, with bags more torque. Think 525/528e in an e30. @eliongater can tell you all about the eta (efficiency) motor.
I think that car is scarily over-priced. Sat for ten years, pumped up the tyres (yeah they seem to have flat spots)... $5k5 one wonders if it was sympathetically recommissioned (all fluids replaced).... or what else has been skimped on? A chancer doing a flip, I reckon. and 250k kms, and coffee coloured? It'd be a reasonable commuter box at $2k or thereabouts. World's gone mad.
