With respect to the buyers' guide, it's most probably the former of your reasons
These cars are robust in areas where the previous generation were not ([unnecessarily?] chunky wishbones for instance), my indie refers to it as being 'built like a tank', which given the state of the roads is definitely a good thing! I don't find myself crashing through a pothole and being really concerned about the suspension like I was in the 147.
Have a look at this thread
, in which a few of us chipped in with our 'reliability roundups'.
As far as I'm aware, there haven't been any cases involving problems with the V6. A couple of oil pumps and fuel pumps have let go, but very isolated cases.
Have you driven a V6 Brera? I've never driven a GTV, but I'm pretty sure they're very different. There was a recent 'discussion' about this here
(although I'm not sure Mr Caine's "experience" is very extensive
). The message to take away from that is to not consider the Brera the natural successor to the GTV. It's better to think of the Brera as a sporty grand tourer/cruiser type car. Like a smaller, better looking 159
I can't think of anyone who has extensively modified a Q4. I think it's going to be tough to lose the extra 100kg. From a drivability point of view, I don't think it suffers from it -- yes it's heavy, but it feels really planted. Q4 is 100kgs well spent. From some quick Googling, I came up with a 0-62 time of 6.8 seconds for the Q4 and 7.0 for the 'S'.
A chap by the name of jbsmith1 has put a lot of effort into increasing the performance of his diesel Brera, and decreasing its weight. You can read about that here
My car has received the Mangoletsi Mod 4, of which the induction is a must just for the sound
It will soon be receiving a SS exhaust, and after that I'll be looking (i.e. saving
) for suspension upgrades.
