I have just collected my car from James @ Chandlers also. (Seen yours Matt when dropping mine off) Originally in for service but had a cylinder leakage test carried out & ended up with head gasket & cam replacement!
From my first contact with James and booking the car in right up to a courtesy follow up email after collection I couldn't of been kept informed any better, with both pictures, costings & timescales etc.
My overall experience was an absolute pleasure & as Matt said James knowledge & passion are clear from the outset which makes you feel at ease & he understands what our cars mean to us.
I also had a 300 mile round journey but it was well worth it.
Thanks again James
