Always helpful, from the same stable as The Alfa Workshop (read, Jamie Porter). Website has well populated "how to" and buyers guides for Alfas and they are trying to populate FIAT Marque likewise.
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.
These guys know their stuff (Fiat, and Alfa too). Very competitive prices, genuine parts.
True Fiat/Alfa enthusiasts
Much less than dealer rates
Genuine Fiat parts and oils, or good OEM equivs
Very 'open' with advice and help
Work on 'who gets there first gets into workshop first', so need to arrive early for while-you-wait service.
Based on a couple of recommendations on this Forum, took my 2018 Panda 4x4 MJ here for its 36,000 mile service. In part because they are nearer to me (in north Herts) than any Fiat dealer. Very impressed by their 'openness' to show you how to do the work yourself on their website... in fact, my car was used by them to create two new 'how to' guides (https://www.fiatworkshop.co.uk/fiat_Panda_1.3_fuel_filter_replacement.shtml). I was there in October 2021 and they were still being very Covid-careful, so never got past the front door. But the service all done for £168 inc oil change was much less than Fiat wanted. Some very 'exotic' classic Alfas in the workshop the day I was there. All booked online and the job done while I waited - I took a walk to the nearby Therfield Heath for a couple of hours. I'll be back.
