SCOOTER BOY
I would be looking for a detail of what was done asap..... that is just shy of €11,500....... WOW........ Allot of money for anything.....
Secondly, what company preformed your annual?? I would be tempted to get a copy of the detail of what was done & send it to a few other companies for pricing.... Just for your own piece of mind to see if you were ripped off or justifiably charged.
The last thing is why did you need a new exhaust system????
4 years & 500 hours seems like a short life to me......
