Can someone help me spawn mesh vehicles?

I'm trying to set up a cars system. All of the vehicles are mesh vehicles. I need a way to spawn the vehicles in on command without them previously being there. I've asked a question like this before and the response didn't work with mesh eg: on spawning the body of the car only stayed for a second before it disappeared and everything but the wheels despawned.

My main question is this: Is there a way to spawn a vehicle new? This would preferably be from clicking a physical object but anything that will work will be great. Please tell me if further details are needed than the below:

-system must work for mesh cars -won't spawn the car in a random location -works by clicking an object in the workspace
