Uncle Arnold and Parks seem to have pretty much sown up the garages in the west of Scotland between them and from my own experience both are dreadful.

Looking to get a service on my Fiat Panda. Any decent garages on East Kilbride or south of Glasgow anyone can recommend

Greenlaw garage in Paisley is excellent.
Had my car in a couple of times for minor things now (filter fitting, noise investigation and tyre supply and fitting)
They are friendly, professional and very well priced. If i remember right i was around £90 for a Conti premium contact fully fitted.
They don't whinge if you take in your own parts to get fitted either like some places.

NOT a Fiat specialist but highly recommended.

what service do you want done?
