London Mechanic PLZ!

Hi,
Had a browse through old posts but it seems like not many ppl know of a reliable and knowledgeable mechanic based in North London area that knows his/her stuff on MK1 cabby's??

My MK1 Golf GTI Sportline has spent the last year SORN and now is the time to get her back on road.
Need the usual things like MOT etc done but i dont want to go to a normal mechanic. Want someone in London (North pref) that knows about the MK1's inside out to carry out all the work.
Need  rocker cover gasket changing, timing belt, 2nd gear crunch sorted and other upgrades that im thinking about doing (suspension,brakes).
At the moment its parked off in Enfield (North London) but i live in Tottenham.

So if anyone can help to carry out the work or recommend a place to take her then i would really appreciate that!
Please any help would be great!!

Thanks
