I always use the Peter cooper in hedge end.
Brought the car from them and had all the work done by them.
After a couple of months of owning my gti I noticed a slight crunch on second gear, so I took it in and they where more than happy to look in to it.
First visit they tried a couple basic things to try and sort it, I took it away but it still not right so took it back and they stripped the gearbox and found slight wear on the 2nd synchro. In the end they replaced 2nd gear and synchro under warranty and now it is perfect.
I have always been treated well down there and the workshop manager has the patience of a saint dealing with a fussy git like me.
