Bit harsh, Ross? My car has 350k kms on the clock, and I still feel happy to jump in the car and drive 1000 miles up and down to PoL, carrying the reserve key as the only spare. Deadly reliable car which has only needed an intake and an airco pump in 5 years of ownership (shockers were by choice). Not only reliable, but cheap too. Apparently she's been a 'daily drive' for all 15 years of her life.
OK, always "oils-and-filters" services done on time, or early, and in my ownership, the big service done by Austin's in Burton-on-Trent. All helps, I guess
Maybe I am very lucky and/or you are very unlucky.
