My Alfa Romeo 159 still turns heads despite being designed back in 2005. And while the diesel still sounds like it should be in the paddock at low speeds, it is a performer.
Not really a nimble around town sports saloon, you can kick it up a notch when you get to know how to drive it. Definitely more of a grand tourer, the Alfa 159 has loads of grip, and apart from a little turbo lag, still provides performance plus.
And for all the nay sayers out there who doubt Italian build quality, I've had no warranty required issues, unlike friends and colleagues who drive BMWs, Volkswagens and Audis.
