My mum bought her 1.4 from there and that went ok, to be fair we didnt have any problems with them
masters of beckenham on the other hand were complete crap! car went in to have its usual coil pack fitted, came back filthy, brakes were shot, clutch had been destroyed, they obviously let the idiot mechanics have a go of it...and it wasnt even fixed, not impressed, coupled with general lack of knowledge and poor service, and idiot salesmen too
I haven't yet encountered any Renault dealership that has been much good though
