A few points based on your comments:
've only had the car about three months and have done about 2200 miles in that time. Before buying the car from a dealer (Stockport Car Supermarket- http://www.stockportcarsupermarket.c...stockport.htm)
, I informed him that I was aware of the cambelt issue on the 147 and that AR recommend that the belt should be replaced at around 36000 miles. I had even offered to pay the dealer a little extra if he would replace the belt. However, he had told me that their garage had checked the belt and were of he opinion that it did not need changing. Also he had agreed to extend the standard 3 month standard warranty to a 12 month warranty saying that if there were any problems with the belt it would be covered under the warranty.
Did you get that in writing, and does the warranty information pack clearly state this also? Unless that warranty documentation clearly states that it will only pay the first £500 of every claim, they CANNOT make you pay a single penny.
Obvious question, but does the car have full service history with all services carried out, stamped and within the acceptable mileages/time frame for each service?
That said, if the cambelt parts have failed due to a manufactural defect within their warranty period you could stand with a claim. But you need a receipt to prove this.
Speak to the dealership that did the 36k service and find out exactly what they did at the service, and if possible ask for a copy of the invoice for the purposes of following this up with AR UK.
If it has indeed failed after being proven to have been replaced within such a short mileage then you could have a claim with AR UK and the manufacturers of the parts fitted when the cambelt was replaced.
I would appreciate it if you guys could give me some idea of how much it normally costs for repairing the cambelt, and also any garage recommendations in/around Swansea (which is where it broke down; I live in Manchester but came to Swansea to visit some family a few days ago...on holiday...some holiday it's turned out to be!)
The cambelt having snapped is the least of your worries. The more worrying factor here is the subsequent damage caused to your valves, due to piston/valve contact.
Quotes will vary dependant on the severity of the damage caused. Obviously replacing 16 valves, and associated parts will cost more than replacing 2-3.
I knew at the time I should have avoided buying an AR, what with all the horror stories...but I was carried away by the looks and stylish appearence of the car...the head gave way to the heart! NEVER AGAIN will I touch an AR with a bargepole! As soon as it's repaired, i'm part-ex'ing it for a decent car that's not going to financially rape me on a regular basis!
Your clearly angry, i would be, but your blaming the car, when infact its yourself that in some respects caused this to happen. Unless there was documentation proving otherwise, you should have had it changed. The responsibility falls on yourself for ensuring that maintenance is upheld and on time. Times have moved on, Alfa Romeo make exceedingly good cars. But neglecting routine maintenance on any car, or leaving anything as crucial as cambelt changes to chance on anything will ultimately end up with this result. Sometimes your lucky, sometimes your not. This time you werent.
Hope this helps.
