Hi Paul, lovely car!
I know it’s a bit controversial but I took mine to Hardys on Stafford Park for the last 2 years. They have to follow a script which includes the dreaded emissions but the guy who does it is pretty fair. So far it’s past twice and that was using their MoT discount code (£28?).
The only warning would be to watch it like a hawk and make sure they know where the jacking points are. Again the guy was fine and was ok with me watching. I was a little worried when he drove it over the rollers but there was enough clearance. Could be an issue though if yours is lower?
Another option is Edgmond garage as that’s also good as I know someone who gets their S2 serviced and MoTed there.
Good luck and maybe see you around Telford!
Cheers Julian
