Volvo V 50 again Reperatur

Hello, I have to get rid of my frustration, sorry. A few years ago we were proud owners of a Volvo GL 740, BJ 1989, bought with 90,000 km. At 300,000 km he ran quite well, but we wanted a new Volvo. So we bought 4 years ago a V 50, 1.8 L BJ 2005 with 16,000 km. After about 70,000 km the throttle valve was broken, immediately after that the alternator was broken, after everything was still under guarantee, we only had to pay the working time (don’t understand why you have to pay the AZ, if the car still ran under guarantee) Now, at 120,000 km the intake manifold seems to be broken, more precisely you can say that only after the disassembly. The good man said, so about 440 Euro without working time you have to expect, if it is this part, assume that we are so with about 700 Euro. I would not be surprised if after that something would break again, this car seems to be a black sheep. The disappointment is great, the next car will certainly be LG, beat Volvo.
