Look at the "makers" page on this site to get an overview of what is available and from whom/where. What you select will depend very much on how much you want to or can spend on your Speedster. All of the makers listed produce a good product, but the more you have to spend, the better car you will get. I personally have a 2000 VS which I purchased used and overall have been satisfied with. I love to drive the car and look for excuses to take a spin, which isn't hard. I'm weak when it comes to this car.
Hang out at the site for a while and you will learn a great deal. We have a talented and informed group of folks who will be glad to share their experiences with you. Enjoy! You are embarking on an adventure more exciting than you might first believe.
