A few regions have this type of thread in their lounges, so I thought I'd put one up for North Wales.
So post up who you use, would recommend or who to avoid with a 10ft barge pole!
I'll start with -
AllItalia 01978 757588
Paxton Garage
Llewelyn Rd
Vron, Tanyfron
Wrexham
They replaced my clutch and installed a Q2 on the GTV with no problems since
The Wheel Restorer 0845 373 4358
Unit 7, Plas Grono Road
Bersham Enterprise Centre
Rhostyllen
Wrexham
They powder coated by alloy wheels last year and did a good job. They are also recommended tyre fitters for Blackcircles.com
Alfatune 01744 25499
Merton Bank Road
St Helens
Merseyside
They're not in North Wales but I can't recommend them highly enough
