Any garage recommendations for the Winchester/Southampton area would be very much appreciated.
Get a price from Jim at IGS in Eastleigh (ex Peter Cooper mechanic from well before it was Peter Cooper, and does a lot of race prep) and Steve Monk in North Baddesly, then go back to Peter Cooper with those quotes, they will normally price match those two. They are both good VW Indies anyway, so you have plenty of choice.
Regal in Swaythling know all about Golf's, but are probably quite pricey, but it could be worth giving them a call too.
