My only comments are:
- Clutch. No manufacturer will stand by their product on this one. This is totally a wear and tear item. I was listening to my neighbour back is new (to him) Porsche out of his property on the weekend ... lets just say flywheel and clutch will be toast if he keeps that up!
- Tyres. Modern FWD cars have very aggressive wheel alignment. Many of these cars now have negative camber on the rear wheels for example and to make them handle they specify performance tyres ... which are soft. My advise is to buy a BMW, a company that understands that if you want a performance car it has to be RWD. FWD are great for family cars or shopping vehicles but you cannot feed 250hp through the front wheels with out MASSIVE compromises elsewhere ... you have just discovered one.
- Clunking noices ... well I would not have worried about this myself except for the teeth breaking off the diff. Manufacturer defect. This would have been sorted out under waranty and sounds like it was ... thus why the grief?
So in the end you have one single issue with your car (ignoring the VDC which sounds like it is behaving normal) and you are bashing the company and yet they fixed that under waranty. I say either cool off and think rationally or sell the car.
Many brand new cars have issues and unless the manufacturer does not fix them you have nothing to complain about. Cars are complex.
Now the big question is: Why the heck did you buy an Alfa Romeo after your fathers experience?
I never advise any friend of mine to buy an Alfa Romeo. I love them, but I fully understand that you are playing Russian Roulet and that every 5th car is a dud. Also trim quality is appalling ... you knew this and yet you still bought one and expected it to be like a German car. Facts are facts, they are built just as poorly as any other Italian product. Quality does not equal Italian, plain and simple.
But in conclusion I really think you are being a bit hard on Alfa Romeo. So the clutch is worn out, as are the tyres and the diff is stuffed ... hmmm, lets see previous owner was a hoon, which makes perfect sense as if I bought a 147GTA the front wheels would be spinning every day
... and I'd be smiling like the cat that got the cream. Yep I'd have to replace tyres ... but you cannot have it both ways.
Good luck, mate ... but I suggest you start complaining when Alfa Romeo stop fixing the issues not while they are ... fairs fair
