Hi,
As far as re-sale is concerned I don’t see too much problem.
I still have all my qualifications if anyone wanted to see them. I worked as a Jaguar mechanic for 3 years and was a mechanic for a total of 9 years before becoming a Transport Manager.
I would write all the services in the service book as a dealer would but without stamping it. Obviously I would have all the reciepts for the parts as well, just to back it all up.
I may have the small service done at a main dealer just so they can “plug it in” and check all the electric gizmos under the bonnet, but that’s a worthwhile £153.
Would this put you off?
Richard
