There's numerous cars around with Star Wars paint jobs. How about this Episode I van for Matt ...
But for real customising, how about an X-wing pick-up truck ...
Or a couple of landspeeders ...
I'm not sure if it's the same one, but there is a landspeeder in America like that second one which is street legal and quite a few people have built "real" landspeeders.
Or perhaps a Battlestar Galactica Viper ...
Then there's this Audi hover car concept called the
Audi Shark (by designer Kazim
Doku too!) that looks like something the Naboo would make ...

(There's more images at the link above, but from other angles it looks less Naboo-like.)
For those without hugemungous bank accounts, there's always the Millennium Falcon windscreen shade from
ThinkGeek.com for only US$20 (plus shipping) ...
