E46 BMW 330i
My second E46 3 Series, a 330i Auto.
This was a nice car, spoilt only by rust and an automatic gearbox that misbehaved on hills.
I spent a day valeting it, only to find that there was some serious rust in the wheel arches, bonnet, and boot lid.
I also realised that new brake discs were going to be needed sooner rather than later (it's had to test for things like this when you only get a brief test drive at 35mph).
It had to go.
