No idea what the planned upgrades are for the 159 in Ti guise, but by god does it look good in these pics. The interior especially so, I love those seats compared to the acres of plain leather found in many cars:
That's a work of art. Maybe if my 147 lasts long enough I'll have one of those next, when they're a couple of years old. That steering wheel looks especially nice. Have they released any pics of the saloon? Not trying to have a go or anything, but I doubt it'll look as muscular as the SW.
