that Alfa would work fine. We had a 164 2.0 Twin Spark, from 1989 to 1998, worked fine for 420.000 km with just the usual care of it, no bigger issues. the best car dad had so far, and he owned quite a lot of cars.
the JTS is even newer, so go for it. the fuel consumption is a little higher than some competitors of the sime category, but it's not that you have our gas price...
the only problem of the GTV is the little trunk, but I wouldn't bother, the look is soooooo sexy, especially in the restyled versions.
you should consider the V6 version, just for the sound.
even being an fwd car it can handle quite a lot of power, Alfa and Honda became very efficient at that.
