You want to narrow that down a bit. There are literally dozens of mfgrs doing kits. From the UK, South Africa, US, and undoubtedly many others. Everything from Luxury tourers to race cars, Porsche 356 replicas, GT-40's, all sort of Lotus clones, Model A Fords, SS Jags, Mercedes, Bugatti's and, of course the various forms if Shelby Cobra replicas, ad infinitum!
The web is the place to get an answer much more in depth than I can give here unless you get down to specifics.
