NFS extra cars

Try websites like www.nfcars.com. They usually have all that is available till date. I don't think they have Daewoo cars though, because Daewoo isn't so well-known. Try more flexible cars like volkswagen or ford. I think you might find a lot of those on any website regarding the need for speed game series. Or, if you want to be really great, than you should try expansion packs. I hear they make those, too.
