I find that with any car as long as you look after them they'll look after you. Alfa have gotten a bad name by ******s who don't bother checking their fluids all year round and leave all maintenance up to the blokes that service it.
They're the type of people who slag Alfa off when their car blows up, even though it's their own fault.
Admittedly, the cam belt issue is a biggy, it would have helped if Alfa stuck the belt somewhere else so it didn't wreck everything else in the engine, or if they used better tensioners. But they didn't, so it's one thing we have to live with.
All cars have their weak points and the cambelt is one of Alfaa, but so what? As long as you change it before it's due date you should be fine.
If people want a car that drives them from A to B they shouldn't have bought an Alfa, they should have bought a Ford. And even then they can go wrong.
Alfas are for people who really love cars and don't mind the niggly things, as they are rewarded with driving the car. My 156 V6 was fantastic, and had nothing wrong with it whatsoever, I loved it.
Not sure why I sold it in the end but I did. Probably because at the time I felt the same way you did, like it was all going to blow up at any minute,
But looking back I looked after that car and it looked after me. It was a mutual relationship. Keep fluids topped. Only race when warmed etc.
There is something more than just owning a car to Alfa Romeo, and it's something that Ford and Vauxhall owners will never understand.
I find if you ask someone what engine their Fiesta has they'll have no idea, but you ask ANY Alfa Owner and they will know. Whether it be male or female, they will know.
