I ordered 2 of these kits so I would have a spare for the stash. I liked it so much I built both. There are 2 complete sets of wheels and a separate hood tachometer included. I put different wheels on each one and the optional tach on just one build. There is no engine, but one could be added from another kit, as the hood is a separate part. The red line tires and decals are a real plus. Don't let the decals soak in the warm water! It only takes 3-4 seconds for them to loosen from the backing paper.
