My local one at Garrets Green in Brum are always helpfull when it comes to my Fords... They had bits and helped with my RS1600i, MY S2's and MY COSSIE's
But admitidly not all are that good and being fair it does depend what you're asking for.
Walking in and asking for a drivers seat, a dashboard and bodykit parts would be like looking for a Lepreachaun sat on a pot of gold dust mixed in with some hens teeth right next to some rocking horse shit- all of which is at the end of the rainbow.
