Quick message to introduce myself

I am lucky new owner of M340's E85 Z4 3.0Si and could not be happier

It is in Silver Grey with Individual Amarone Leather and only covered 47k.
The car does not want for anything, but currently sits on H&R springs and I would like to put it back on the originals.
Any good indy to recommend to do the job not too far from North London?
Anyway, I hope restrictions will end soon so that I can go for a proper drive and meet fellow Z4 owners!
