This is one of my favorite toys for Christmas this year. Chicco just came out with its Turbo Touch Speed Truck, a carrier truck/race track all in one. In truck form, it is able to carry up to five Turbo Touch vehicles at once (sold separately, although it does come with one). But it also transforms into a 3 foot long race track, complete with actual traffic light signals that start the race. The track also has a sensor that detects when the car crosses the finish line, causing the traffic lights to turn green.
I found this toy to be very well constructed. I also like how it comes put together and with the 3 x AAA batteries included. You can literally just take it out of the package and start using it. Get it at Toys R Us today.
