Gary, the reason nobody wants to answer your simple question with a simple company "A" is the best and then company "B" is because it really isn't that simple. Different car manufacturers provide different versions of the car. I think, as with most things, you do get what you pay for, but the real question is what do you need and want your car to be. After much research I have come to the conclusion that for a speedster the options are pretty much limited to Vintage, Intermeccanica, JPS, Specialty Autoworks, and Beck. Do a forum search and look at only the vendor category to get started and you will quickly see the differences. The prices vary among the builders, but so to does the cost and quality.....it really comes down to what it is worth to you to have the different options on your car......for sure the Knotts show in April will allow you to look at all of the major players....but, read the old forum threads to educate yourself......I realized only after asking some very dumb questions how valuable the forum search can be.....good luck
