Rarely see 08 + 630i, any for sale at the minute? Consideribg you can buy an 05/06 630i for 4/5k , 635ds are around 10/11k, would a 630i fall in the middle? If there 750 tax then they do make good sense.

I see a 645i on dondeal with a whopper receipt for engine oil leak repairs ! Didnt realise they were so common!
