'05 Elise - weekend / sunny day car for me, got it used with 17K miles. It definitely needed some pampering after being in NJ for a year. After a good cleanup and full dealer service it's good as new.
So far I'm planning to keep it stock, just changed couple of minor cosmetic things and lighting.
Update: powdercoated the stock sport package wheels in flat black - will make it much easier to get them looking clean now.
5000K HIDs help a lot at night, chrome blinker bulbs clean up the front end.
For now - couple of pictures:
Couple interior shots after a good cleanup and some interior upgrades:
