Re: Brera, and the 3.2
I guess it depends on just how big the humps are.
My 3.2 Brera clears them OK, but I'm always gentle over them.
I've only done approx 10k miles in mine so far, but oil use has been negligible.
Anything else to look out for?
Well, if its a new one, then probably very little. No more than if you were buying a merc bm or audi.
Some people have reported issues with the drivers seat developing a bit of play on the runners (this is sorted under warranty), the rear lights can get water in the lens, & the occasional glitch with the alarm going off when it shouldn't. Again, there is an under warranty fix for that too.
Oh, & fuel consumption. Be prepared for low 20's mpg.
If that doesn't put you off, then you'll be a very proud owner of a very cool car.
