I had a full 4 wheel alignment (Hunter) at Cooper Barnes in Linton last weekend.
Having tried a couple of the franchised places around Cambridge with poor results in the past, I was impressed with these guys. It took them two attempts to get it 100% spot on as after the first the steering was ever so slightly (3-4°) off even though it tracked nice and straight. They weren't happy until I was and had me back a couple days later to sort it. The managing director even got stuck in, explaining the whole process to me, inviting me to have a look at what they were up to. Being a body shop I assume they have a fair bit of experience setting up suspension from scratch.
Prices were reasonable too; £25+vat for and initial check then £25+vat per adjustment up to a maximum total cost of £100+vat. All before/after print outs provided.
They were very quick responding to emails for me, got to be worth an ask
