My French pile of screws…

My dream car is a nightmare!!! I don’t know where to start, maybe with what wasn’t broken yet? Purchased in 2009 at the dealer’s first hand 68000km 407 SW 2,0 136hp back then already replaced the first wing joint just before!! Ok I can’t list the repeats by order anymore but here’s the overview: -> 4 new support joints on the front axle in change right and left -> new axle driver side -> new drive shaft because this gives me while driving och war!! ->new cooler -> new clutch -> error exhaust gas (secondary air filter ) -> right now a new servo pump is coming in, and with the brake light switch something is wrong. -> constantly any errors in the display that are mostly not correct… My question am I an isolated case?? To the info of the car has now run in 5 years almost 100000 with us.
