I think some models are downright bargains - mostly because there's no comparable cars here. Like those with the M40i badge - 3 liter 6 valve little monsters they are.
The 5 series is a great car, I had 1 and almost got a second - with theh 5 year warranty on them, the 530e, you have 184hp from the engine and another 109 from the electric motor - which sounds like fun to me.
You won't regret it IMO.
