Not got this blokes permission to put this on here but I'm sure that he won't mind a bit of free advertising.
While in the process of buying my first GTI, I asked the advice of the bloke who works at/owns Taber. It's a small garage in Bexleyheath specialising in VWs. He gave me good, free advice over the phone. When I got the GTI I took it to him to do the cam belt and other bits and to have a good look to see if anything else needed doing. He charged me a reasonable rate and didn't have me over. He has since given me more free advice about my sunroof issue. Nice to find some one genuine in the motor trade.
