I was looking at the face lift for a while (going from 2005 to more recent years) but then I always fall in the same dilemma of money spending . . . Is it better to spend your money on facial improvements that makes the car look really nice but will stay fresh for only a few years, or to spend it on performance which aren't appreciable by others but makes the ride a lot more fun to drive . . .
Ideally you'd do it all but then for the same price of that improvements you can get a better car

I guess it always depends on preferences, and passion, but I always seem to fall back on performances
The best is to do it like Crossie did: when it gets bad and you need it fix, rather then just fix it you improve it! That goes for a lot of wear items from body work, to lens aging, to suspension and brake ware...
Final thought: Does anyone think it is sometime nice for a vehicle to keep it's styling from the year(s) of fabrication so it retains its original history? just a thought... (that doesn't really apply for the sport trims obviously if within the same year)
