small workshop down the end of St James Mill Road (near the station, behind Maplin)
Run by a chap called Ben who's pretty patient, helpful and knowledgeable about porsches in general. About 20% of their work is porsches - certainly I saw around 8 when I was down there. Not keen on doing nonstandard work ("we don't do boy racer stuff really") but will fit parts if supplied.
Pretty quick to fit me in (got the impression I got lucky tho as they seemed very busy later)
Took me round all work done afterwards pointing out what they'd done and showing me the parts replaced. Very pleased with level of service, patience with someone who's not that knowledgeable mechanically, and the effort they went to to make sure it was all done right. And put up with me phoning a lot
