As Carey says, it's a good idea to buy used to find out what you like and don't like. I like his idea of getting a used one, placing an order for a new one, and sorting out your wish list.
I had two used Intermeccanicas (a Roadster and a Speedster) which I enjoyed, before I commissioned my IM6 build, and I'm happy with what I have now. You really need time to get used to these cars - how they drive, how they operate, etc. They are not Miatas, and require a special type of owner.
The worst thing you can do is buy one on looks alone. A colour combination doesn't seem so great once/if the problems start.
