Sale of Goods Act does apply to cars when bought from a dealer - not private or auction.
Should be Satisfactory quality, As Described, Fit for purpose, And last a Reasonable length of Time. So technically you could very well argue it wasn't of satisfactory quality and didn't last a reasonable length of time. Legally your gripe is with the dealer - not Fiat.
I think I'll be looking for a decent extended warranty if I keep the Bravo beyond its third birthday.

Good to know this difference. Actually, I´ve never deeply studied English Law, mostly because it´s common law. I´ve read some papers and some studies about Good Faith in English Law, but just for curiosity. And If I remember, the Good Faith Principle is not mostly acceptable in England. Anyway, I´d love to know more about consumer relationships law in England.
Anyway, in Brazil, doesn´t matter if you bought a car from a dealer, private or auction. If the some part of the car fail for some reason that not harmful usage, it doesn´t matter if you´re the first, second or third owner. Fiat has the duty to solve the problem. Actually, you can choose who gonna pay. I would choose Fiat, of course. Fiat has the money. In this case, you don´t need to prove who is the responsible for the fail in the gearbox, for exemple. Fiat, on the other hand, has to prove that the system fail because of you or a third person. It´s very cool. And work perfectly. This changed the whole system in Brazil. Nowadays, if you choose to open a business in Brazil you have to have in mind that, if something goes wrong, you are responsible, being your fault or not. The consumer just say "hey dealer, I´ve both this thing and it´s not working well". That´s all you have to say here. From this part ahead, the dealer has to prove that the thing is not working well because of you or a third person. If the dealer cannot prove, well, the dealer has to pay. I can say everything works now. No more abuses from dealers.
