Why can't I find a good garage in North London

Hi All

Does anyone know a good reliable garage in North London? 

Had a wiring issue which got resolved but the car has been there 6 weeks, and still not fixed any of the running issues - because they can't be bothered and isn't a priority.

I need to get it moved to a good reliable garage that actually has the time and capabilities to fix a Mk1. 

Was going to send it to Quiffs and heard great things on here, but so bloody far away from North London.

Kinda stuck! And feeling a little irritated
