If you're thinking 'looks' than power....

Nice set of alloys
Decent exhaust back box
tint the rear windows & the boot window (with a legal tint) unless you have the privacy glass, or you could find a scrapped titanium model and get the privacy glass out of it and retro fit it to yours....
Add claimair window deflectors....

just a few ideas, but each to thier own n all that....
