I have just had MOT and service at Grasington Garage, Long Itchington, which I found on the Good Garage Scheme website. Very friendly and efficient service, the proprietor evidently has a Mk1 himself. I would recommend them to anyone in the area looking for a garage.
I have previously used Sam Goodwin in Nuneaton, who is very good, as everybody says, but a bit of a long journey for me.
