Indy recommendations near Kettering Northamptonshire?

[ArthurSleep]

Hi everyone, first post on here for a while.

My '55 plate 3.0D is coming up for a service (first one since in my care) & I'm looking to establish a relationship with a good local indie rather than go Wollaston BMW in Northampton.
Anyone local got any experience?

Choice is probably between:

http://www.richardsautos.co.uk/index.html (the closest)
Mtek in Northampton (Seem to have a good rep)
http://www.autobarnltd.co.uk (Again fairly local but no feedback)

Anyone on here had any experience of the above?
Cheers in advance...
