Get in touch with Paul (owner) at Viezu. Bet he has plenty of his Tuners near Wales if not there already. Tell him I sent you and pass my regards please (Fred, SH/CN)
Plan a good 300 pounds and he'll take you in as a customer I'm sure. Don't be offended if more, worth it, trust me there. In Milton Keynes Aug 22~26 and I want to try your car, I'll lend you my rental in exchange
