106 Rallye Engine specialist recomendation

[Itsallicanafford]

Good afternoon all. can i ask for a recommendation please. I have a S2 106 Rallye and i am looking for a good garage to work on the TU5J2 engine.

I am based on St albans so preferable within 50 Miles of London. I'm not looking for performance enhancements, just a good specialist garage which can give ongoing support on keeping things healthy.

Many thanks in advance.
