I've always used Dave Pullan - Carmaster on Camwall Road. He's a great guy and has always done a good job. Stands to reason why he's always busy and he's got a good few mechanics working for him now.
A bit late now but, Yeah Mike Redpath is a decent bloke. Very tidy facility down Camwal too. Mr Robinson at Smartstep down Claro is good too, pretty straightforward guy, no teeth sucking!
