They are based near Stockbridge/Salisbury, near the A30/A343 junction.
The proprietor (James) is someone I know well & trust, based on positive experience when he was with another BMW specialist in South Hampshire. I believe he set up Bromspec earlier this year. Very friendly & helpful guys. James in particular deserves a medal for having me as a customer. As I'm hyper fussy (bordering on obssessional) when it comes to my car. Yet he always has a smile/responds positively to my sometimes OTT requests and goes the extra mile to help out. Phil (who is his partner) is also a very helpful guy (mind you, he's had less exposure to me !).
They just rebuilt my VANOS with new "O"rings, oil pump disc & a refurbished solenoid (I'll be doing a post on this elsewhere). Plus fitted my RallyRoad Brembo caliper kit and some other jobs. No surprise |(to me) they did a cracking job at a very reasonable price. I'll definitely be using them in future. Only small minus is the location is rural (no "to the door" public transport links, so far as I know). However, they aren't far from Dean or Salisbury stations & I'm pretty sure will arrange drop-off/pick-up.
No connection with them other than as a very satisfied customer.
PS this was on my E46 M3 Convertible
