Hi Jen - I am currently going through the process on a 2004 Caterham bought out of state. Titling was a dream (about 15 mins) in the MVC once I had the right documents (which is key!). I got it titled as a 2004 Caterham without an issue. Registering.....well.....the inspection process is driving me slightly nuts but I can finally see a way through that. If you are interested I have the inspection regs I can get scanned and email to you. Reading them you can get an idea what is likely to cause problems on your car. Strangely I am having most hassle with insurance....
I am happy to share experiences if you want to know more.
cheers
