Both of course !
The 147 is the best traction(with the 156 - same platerform) at the moment, very quick in curves, very silent, very secure, a real modern car ! And selespeed is great........
The 75 hmmmmmmm It gives me this kind of old-fashioned pleasure.
The V6 is wonderfull.
You need "big balls" to drive it fast but it's a real pleasure (no electronic except ABS).
I've already driven it over 400 000 km and It will be hard to sell it (I,ve a good proposition coming from a race school and I'm slowly thinking It would be great as "end of life" for my old friend).
With the 75, i got the same problem you get with your Wheels : I've 17" alloys on it and I had to mesure and calculate a lot to find a solution.
Finally, I ordered standard wheels and let them remanufactured especially for the 75.
