Review: A fun new building experience - This was an interesting build. I've built a lot of LEGO models over the years and this build was much like that experience except for the many parts that are nothing like LEGO parts. There are very flat parts and odd shapes compared to what I'm used to, but that's a good thing because it creates a sleek end product that is not as blocky as some LEGO builds. I'm very happy wire this new Matel building set. It's also cool to get a real Hot Wheels car as a bonus. I hope they branch out to other types of builds, not just the Hot Wheels cars.
Review: Fun to build - Assembled very well with great directions! Cool model and fun to build.
