I have used The Alfa Workshop for many years and before that had regularly visited Jamie Porter when he was "working out of a barn" (no disrespect at all!), and I have owned a string of Alfas since 1986.
More recently The Fiat Workshop has serviced and diagnosed my Panda 4x4 TA - I only have good things to say. There is no pressure to do something and they certainly don't "fire the parts cannon" at issues.
I don't give 5 stars

to anyone!
