I've just entered a fault onto the problems forum that can hopefully be answered but if I need to find a good mechanic/diagnostic technician can one be recommended?

A few years ago I took it to a garage who had it for 3 months saying the computer said I needed to change a whole host of things - it ended up being a simple broken spring in the throttle throat! I felt I was paying for the his training! Can someone who knows Daihatsu in East Anglia or anywhere be recommended? Thanks. Chris
