If you're in/near Wales then your closest place may be Powerstation....

I take my car there (from SW London) as they specialise in Scoobs, but they've always got a Cozzy or 2 in being worked on

I was getting mine seviced there last weekend and they had a full on race spec Saph in the carpark. All stripped out, caged, racing tyres the lot.
