This, of course, is the other thing that happens on the service - the mechanic will spot a set of belts which are about to snap through degrading over time and advise you to get them replaced. If you don't have the service done these things won't get spotted and you could end up with a nasty bill.

Everyone seems to ignore servicing when buying UJM but if you do the comparison you'll realise that it's not that much more expensive and sometimes cheaper!
