A big thank you to all. The service and repair you recently completed for me is second to none. The way I was kept informed was great. Why can other companies not do this. Yes, I had to wait a few day,s but fully understand what happens when a company is busy. Well worth it. I shall certainly recommend you. Well done and thanks again. Excellent.

Wonderful job on my ecu for mercedes Class A Wonderful job on my ecu for mercedes Class A 5/5

I am really happy with your job, the part has been repaired in time as scheduled and I have put it in place and my car is as new ... Really great job, I would kighly recommand your company... Just one remark, do not recommand UPS for the clients located in France, I have scheduled three appointments but they never came to pick up the parcel ! French Chronopost is much quicker and as rapid for 100 € less ....
