In retrospect, having read this last night after a few glasses of wine, it all seemed a whole lot worse than it is. So apologies if I have called your car something it is clearly not.
Everything you talk about are all signs of minor niggles that once put right, you will have a great car. Yes, it is not right that you should have so many minor niggles, but some have them, some dont. Same with all marques.
I had a Fiat Stilo a few years back that had airbag failures, (not sensors, actual bags), coil pack failures, clutch failures all within the 12 month mark - that is a lemon. Yours, whilst, taking the shine of your purchase, once fixed, you can be assured you will have a niggle free ride.
Alfa Romeo Guilietta QV, white, fast, and lots of fun...
