Trustworthy mechanic in East London - E17 ?

[Lexual]

I'm after a mechanic in Walthamstow, or one locally that will travel to Walthamstow.. my 2001 Saab 93 broke down a week ago just before I went on holiday. It has battery power but just clicks/taps when I try and start it, maybe the starter motor or ignition cassettes..

Can anyone recommend someone who may know Saabs and isn't going to charge a fortune to take a look?

Thanks..
