Shortly after purchasing my Ford GT, the GTX1 was introduced at the 2005 SEMA Show. I knew I wanted a X1 and the decision was solidified when I saw it in person at the 2006 B-J in Scottsdale. I was one of the early people to sign up for the upgrade and purchased a 2nd GT to be converted to the X1. Like all the early people who decided to do the conversion, I had a long wait while all the production problems were sorted out. I received my car 3 weeks ago and have logged about 1200 of some of the most fun miles I have ever experienced. The X1 takes the GT to a whole new level. It has far exceeded my expectations and is the most exhilarating car I have ever driven. If you own 2 or more GT's, the only reason I can imagine not to convert one to the GTX1 would be that you simply do not like convertibles/roadsters. I expect all the GTX1 owners on the Forum to be in agreement, but if you own 2 or more GT's and have not made the decision to convert one to a GTX1, I would be curious to know why you are still on the sidelines. The price isn't going down and neither is the excitement.
