That's a RUF front Bumper you have there or an aftermarket replica. Very nice and very uncommon.
Enhancing the interior can be done to the point of total transformation but very pricey.
The biggest way to spice up the interior is to have the center console where your arm rests, (called rear center console) painted to match your exterior. Not cheap but will change the whole look, since you have a very nice color (arena red?).
The other thing you could do is update the steering wheel with a grey three spoke like on the 2000-2004 Boxsters and 911's. That four spoke you have is kind of old school.

p.s.
don't know if its your camera, but your leather looks like its in need of some deep cleaning. I would sugget trying to find some 1Z leather cleaner. Its made in Belgium. It's the best leather cleaner I've used. Will make it look brand new when used with a terry cloth wash towel.
