Felix,
What the guys are telling you is good info. Here are some more points to ponder. You can get an all-made-up-from-scratch welded tube chassis or one built around an old VW pan. The first is a new car, according to some states, and the other is an old car, redone. Could be some advantage wrt insurance and titling in the latter case, as having that VW VIN can make a difference. Some VW pan designs include a welded tube subframe that makes for a very tight ride. Independent rear suspension and 4X disk brakes put the roadworthiness at a level that I think Dr. Porsche would admire. Creature comforts in NY year round are going to be hard to find in a Speedster. Dry cold days are going to be manageable, wet/snowy ones are really going to try your patience. Have you considerd a Coupe? Also, the convertible D design (higher windshield, roll-up windows) could be a reasonable deal. Some builders will install roll-up windows in the Speedster versions. The Forum here has some threads on gas fired heaters, so search for those and get a feeling of what that means. For a builder, I selected JPS MotorSports in N. Hollywood. Did this based on personal praise for the principal there, John Steele, offered to me by many of his customers, and info found here in this Forum. Sealed the deal via a visit to his shop and spending most of a day with John asking a zillion questions, looking at his cars in work. Most here will say that the JPS fit and finish is as good as it gets. He is building my car as I type, so you can take my recommendation w/ a grain of salt, as I have yet to drive the beast. JPS also makes Coupes and two Outlaw style Speedsters: flared-fender, in two "temperatures": elegantly flared, and in-your-face flared. Go to the JPS website and look at all the pictures. Call John and talk to him.
