I took mine to the dealer i got it from for a service and cambelt change back in August, they told me it needed the cambelt changing at 40k and quoted me £370

I took it to a different dealer and they told me it doesn't have a cambelt, it's chain driven which only needs attention if it's slipped, just out of curiosity i phoned 2 other dealers and they said the same....chain driven. It just confirms what i always knew that Gilbert Lawton Manchester are complete tossers who only want your money for nothing in return, also told Vw uk about what they said, still waiting for them to ring me back, it's only been 3 months
In the end i took it to Vw Bury and got a service for £125. G.Lawton wanted £180....joke !
As for the top speed i've never floored it...sorry.
I'm getting 94 miles out of £10 around town....not bad really.
