I'll never use any kind of chain or fast fit centre. The clue is in the name - they're 'fitters', not mechanics (although the first part of that is an insult to actual fitters), and the whole idea of doing it fast usually turns out to mean 'rushed and uncaring'.
All people need to do is ask a bit of advice to find someone more local and personal who can be trusted.
When I moved down here, the supposedly useful 'Good Garage Scheme' website led me to a place that virtually charged main dealer prices.
Now after a bit of asking around, our cars go to a father and son in an old railway shed, there's more junk in it than Steptoes yard, I'm not sure even if the patriarch can read or write, but they know what they're doing, do what they say when they say they'll do it and charge what I consider reasonable rates. Sorted.
