    I bought this for my nephew who is 8 for his birthday. It took him rough 8 hrs to build and the instructions were easy for him to follow. He loved every minute if building it. Highly recommend for any kid.

  9. TUPPA

    Attention to detail is required fir this build but worth the effort and fun to watch the build work.

  10. ExperimentalMind

    This kit was fun but I enjoyed the Shelby more.I had an issue with my push down mechanism. It would either get stuck after pushing it down, not allowing the car to move or it would push down correctly but then pop back up a little stopping the car all together. This made it very hard for my daughters and I to race both cars side by side. The Shelby would fly smoothly and the Porsche would get stuck 80% of the time.The car looks good but the push down mechanism worked much better on the Shelby.
