Here are a bunch of small chibi-style mini vehicles that I have made over the years for my lego city characters.
This is a series of vehicles called MiniCars. From the top down there is a police MiniCar, Jeep MiniCar, Space Center MiniCar (and VTOL SC MiniCar), another Jeep MiniCar and a blue and gray standard Minicar.
This is a trailer I built for LEGO city Fiat type cars. Then there is my modified version of one of the afore mentioned cars.
These are two variants of the three wheeled electric cycles, the first is the street variant and the second is the off road version.
These are some miscellaneous mini vehicles. From the top: Luke's Atv, a Sensei's iced creamery delivery vehicle, and the MK1 PedCar.
