This is a pack of low poly stylized car models. Currently, it contains 10 models; Ambulance, Fire Truck, Ice Cream Truck, Taxi, Town Ace, Retro, Luxury Car, Picnic Truck, Ice Truck, and Picnic Family Car).

It is super easy to use the pack. Just append the models by collections to your blend and you are good to go. 

In the latest update, you can edit the color of the model, Glass color, roughness, and even the headlight and taillight on/off function straight from the right properties tab. No longer need to dive into the node group for that.

(The price of the product may increase over time as I am adding more and more cars to this pack.)
