So after messing around with the loans company and seeing plenty of cars I've decided to go with a 57/08 plate golf gt sport tdi 170, although am yet to find one as there was an issue with my loan being paid out - sorted now.
My reasons for this over the above mentioned cars are that manual 330ds are rare, and even rarer for a decent example in my price range. Parts and the lack of a similar vcds also plays a part. I know the 330d would be lovely, but it looks like I can pay less for a lower mileage, better condition, newer golf tdi 170. I looked at many a4's and they just stopped exciting me really and looking into tweeds comment on the oil issue, it doesn't sound too good.... I know all about the dpf and injectors issues with the 170 tdi, but I will eventually remove the dpf and get it mapped (and the injectors have been recalled) so hopefully this will be the right move! Thanks for everyone's input, I'll get some images up once bought!
