6 years old next month, 24K miles, only gets light use mostly on 5 to 10 mile trips to shops, does about 1,200 miles a year. When should cam belt be changed & what should it cost about?Main Dealer service reception said with my use every 20 years, cost £370. Their mechanic recharging my air con looked at alternator belt and said if that is original belt (it is) it's as new so cambelt should be OK for a bit. Nationwide Autoservices computer says change at 144K miles or 10 years. Others have said it should be done now and they have had idler/tensioner go at 23K miles. Am I living on borrowed time or has it not reached recommended period/miles? Other than fuel gauge started sticking last month, recharged air con this year, radio/CD changed warranty at 29 months, BSI & ECU firmware updated due to couple of minor things under waranty (transponder misread, trip meter blobbed). I am happy with the car as my mobility scooter loads in it easily with ramps & don't have to remove any bits just fold seat & tiller.
