"I bought 2, one for my 7 year old son and one for myself since I am a big Mustang fan. Build was fairly easy, but, the attention to detail and design is really cool. Absolutely love the rear tail lights. My son and I built ours together in about 30-45 mins and he only needed putting on the sticker so the stripes line up on the roof and door panels. For $15 these Speed Champions sets are a no brainer for kids and adults. We will be completing the entire S.C. individual car sets!"
