Have been there for two consecutive maintenance checks for a scooter. I didn't have any problems with it, but I prefer a peace of mind so I have it serviced and inspected regularly. I can't tell much on the price side, at that time I didn't mind - not cheap, but at least they display it on the web site and the list of checks they do* (see below) looks good. Staff was always friendly - no complaints on that either.
The thing is, right after the second service (in about a day) a fuel line cracked next to the carb intake and started spilling fuel on the engine. It took me a few days (I thought I had nothing to worry about) to realise something was wrong (it's actually funny if you think about it - I though it was the smell of construction paint, until it started stinking like hell and I started feeling it even when riding), and when I looked inside - F#ME! - I would have bricked my pants if I new I was riding an unlit torch all that time! Had to replace that line sodding myself after all.
Interestingly, at least the last service I had, amongst other things included "fuel lines and tank inspection", non of which I guess never had a look at, as the line I replaced looked quite bad on the faulty end. That makes me question how much of the stuff from the list (that I paid for) has actually been done, and what would it have been like if I had a problematic bike.
Anyway, that's exactly what I'm trying to avoid, so next time I'll pick another place for service.
