manufacturing flaw - the car

In February 2006 I purchased a brand new Opel Signum 3.2(2004) from Opel dealer (M/s Mannai Motors) in Bahrain.
It now has 57000 km on the clock.
Just before the 35 000 km service, the master break cylinder had to be replaced,
After the 45 000 km service, Ac Evaporator had to be replaced. It now has 57000 km the service manager says again Ac Evaporator must be replaced! How come the Ac Evaporator has got the life of just 15 months???

It now has 57000 km, the car has got starting trouble. The service manager said Fuel Tank Vent Value and Fuel Canister to be replaced. Strange being the dealer for this vehicle, these parts are not available in Bahrain! So He had to order one from Germany for which I had to pay in advance!! Which cost almost fortune-Bd-205/=(Usd 539/=) I had to wait for 15 days to get the part. Now for last 1 month my car is in dealers garage (M/s Mannai Motors), they could not fix the problem yet. The service manager says they are in touch with Opel office in Germany. Now I need to know what remedy available is for me;
MY complaint with Opel is:
How come Opel spare parts are so expensive in Bahrain.
Why Opel is not having proper garage with trained mechanics in Bahrain??
A brand new car driven off the floor should not have so many big problems before it has 57 000 km's on the clock, unless the car was (a) poorly manufactured or (b) poorly designed.
Either way, I feel that I have been cheated. I was promised a decent car and was given a machine with endless faults. I drive the car to work and back (about 15 km) a day, on a normal road, and is in a constant state of panic because anything could go wrong with the car and kill us. It is unsafe. I have no idea what Opel are going to do to rectify this situation; it is ridiculous to be in a constant state of panic as to what’s going to break next when I get into my new car!
