I had my E39 530D superchipped yesterday at A1 autocare, their service was so good I decided to come on here and let others know. The performance difference is extremely noticeable and well worth the money, the car does not shake now when idle and is just generally a nicer car to drive! Richard (I believe he is the owner) was very chatty and is also a fellow BMW fan, he even replaced a bulb for me free of charge! Lovely friendly service, free Tea and Coffee while you wait! Highly recommended! A1... A+!!!
