Before I bought my E60, I looked at several 4 and 5 door 335d's in't UK in dealers and private sales.
Prices ranged from £11k to £16k for 09 and 10 models, plus say €6k VRT.
Can't say on the 2 door models, but I'd say looking in the UK and adding VRT then taking a bit off would be a good startng point.
