Toyota RAV4 3dr , SLK55amg, ML320 (2 ) A210 , E320 ( all gone )
I can also recommend Continental Cars, used them for my E class and my first ML, have a newer car now so using MB dealer in Swansea but would use them again
They quoted me more than MB for a gearbox service...
Was that because they were going to change the fluid in the torque converter as well , the dealer would only have done a standard ( partial ) fluid change by just draining the gearbox
Another vote for Continental Cars in Cardiff and for Stuttgart Garage. I've used both now. Continental did the B service on my CLS500 yesterday and it's purring like a kitten. Stuttgart looked after my 190E and E270 a decade ago and were very good then.
