I wouldn't think there's enough interest for the DW guys to stock anything, but I'm sure they could source most things if you asked specifically.
Look how many S-bodys there are, this is enough to keep the DW shop going. Now look at the number of BMWs, all of different types (e28, e30, e36, e34), there is only a fraction of the number of nissans, I wouldn't blame the DW guys for not stocking anything - although obviously I would appreciate it
Yeah, like the guys have said, there's too much variation and not enough demand for the BMW stuff, so we don't stock it, but we have accounts with most automotive suppliers these days, so if there's stuff you want and you don't mind waiting while we order them in. We can usually sort bits and bobs for you guys
