I think you are right. I shouldn't decide by one review. I am based in London.Go elsewhere if you're that concerned - I wouldn't be by one review, in fact I'd go on word of mouth if at all possible. Where are you based - perhaps someone can suggest an alternative.
It's also good to get into regular preventative maintenance - don't wait until it needs fixing (especially when it comes to brakes and tyres )
