I called Wimbledon Automatics after the gearbox on my C Class Merc started playing up. I had the fear of huge costs and being told it was a new box required. Not so, Derek was incredibly helpful and informative and, using his special kit, advised it was a replacement component rather than the entire box itself. It was left with them and they repaired it like new. It runs so much better than it had done for months. I was kept in touch during the repairs and the costs were as quoted so I knew exactly what to expect. A great service from the team. I would definitely recommend them.
