My experience with alfa reliability is that going by the facts it's pretty good, but people like to reenforce stereotypes.
I have parts delivered at work for convenience and I do maintenance and simple repairs myself. My coworkers claim I'm always getting alfa parts delivered, but then conveniently 'forget' that I have 2 of them in the household, both of them racking up above average annual mileage (between us the mrs and I exceed 45,000km yearly).
They do seem to be suspiciously quiet about when their cars need miantenance/repairs. Case in point, my german coworker likes to talk down any car that isn't Audi, Bmw or Volkswagen, but hasn't responded in any shape or form when I asked him this morning where he parked his Audi apart from saying he was dropped off.
I did overhear him mentioning to another coworker it needed some work doing, probably doesn't want me to grin about german reliability...
Btw, that car has similar age and mileage as mine (both 9yo >200,000km turbo diesels) and has had similar maintenance/repairs, par for the course like I said.
Now, as I'm not buying cars from new, I like that your average person shies away from 2nd hand alfas, but I do need people to keep buying them new, obviously, so it's a bit of a mixed feeling.
Btw, you just bought a car with a clutch close to failing (not necessarily known by the previous owner) that's hardly an alfa romeo issue. It's experience gained, the wallet hurt tends to aid the learning...
