MGtastic in Chaderton is the closest I can bring to mind. I've only delt with them once & that was for a part however he was knowledgeable & helpful. There was work going on & to a high standard, give them a bell : 07711 097597.
It's a shame when long standing companies pack up & go home but they have to make a living or they've just had enough of being buggered about with & I can't see there being many MG Rover cars in Bradford now. Last time I was through there it seemed that every forth car was a black BMW with blacked out windows, rusty Mercedes vans which had originally been white, black Mercedes also with blacked out windows, the rest were Prius taxis, usually silver.
Let us know how you get on with these guys, if you decide to use them. Sometimes even the keenest of spanner jockeys finds themselves out of their depth & if your within their catchment area & knowing they are reputable might just prevent accelerated hair loss & the need for Cobbers extended lexicon of profanity.
