Hot Wheels City Toy Car Track Set

We surprised our 5 yr old son with a whole bunch of these Hot Wheels City pieces....the ice cream shop, car garage, parking garage, pizza shop, burger joint, hospital, police station....about 15 different ones. We also got 2 sets of the tracks which I was super glad I decided on getting 2 sets instead of just 1 set because with that many shops we got, you need more track! And let me tell you! He was over the moon! Yes, all of the sets need to be assembled. They are pretty easy to do. The instructions are very clear and include stickers, if any. None of the sets we chose needed any batteries. Each set comes with its own Hot wheels car too! And it's usually a car that sort of matches the set it comes with. Ex:Donut Shoppe- Donut deliver van, Police Station-police car, etc. So it was like he got 20 new vehicles also! He loved deciding how he wanted to set up his city and how he wanted to lay the streets. They all connect to each other and to the track pieces. He even had an old Hot Wheels gas station set from maybe 10 years ago...and it actually fit together with the new sets! He's always rearranging his city. These Hot Wheels City sets also fit together with the Match Box Action sets. Which is great considering we bought a few of these sets as well thinking they were the Hot Wheels sets. Although they are not the same brand, they ARE both owned by Mattel. So, I won't feel bad saying this....the Match Box Action sets are a TEENSIE bit better than the Hot Wheels sets. Not that these HW sets are bad in any way...they are not! But thr MB sets just have that little something extra about them. It's like they are a level up. You would know exactly what I meant if you had them both in front of you. But our son didn't even notice. This was a great purchase for us for our son! We were all very happy with it and our son still is!
