I think UCP is a great site, with a great database... But I do miss one manufacturer (or I must be looking really bad) DONKERVOORT!! I come from Holland, where Donkervoorts are made, and I do think (since there a dutch mods too) it should be added to the database. It has some great and nice looking cars, not to mention they are quite exclusive. Sow please: add some Donkervoorts to the database!!
p.s. I wouldn't mind to help!!
