About vehicles

Vehicles is the largest category on Enviglo. It covers drivable chassis, static models for set dressing, aircraft and airport ground equipment, buses and coaches, trains, boats and emergency fleets.

A chassis is a working system rather than a mesh: suspension, gearing, sounds and seats, usually with a settings module to tune it. A model is the body and detail. Plenty of creators here sell both, and the product page says which you are getting before you buy.
