I did lots of ringing when I looked..
Try Mo Khan at JCT 600 hull they had a 3 door red dsg with buckets coming but I wanted manual. Otherwise it was perfect spec. Was a while ago but I think it wasn't due in until February.
Try Mike Brain at Crewe VW where I got my 3 door manual red CS. Think he has a white 3 door with buckets and think he had a carbon but don't think it had buckets. Mention my name (Andy) if you call him
My local dealer in Ipswich (Marriott motor group) ask for Eugene brand manager he called me and said he was offered 2 cars from VW stock but don't think they had buckets.
Think vindis Cambridge had a couple of cars coming in can't remember spec.
Best thing is do what I do, set aside a couple of hours, picks a few dealers and get on phone !
