If your existing car can’t be towed with its wheels on the ground and if you really need to bring a car your choices are to purchase a car that can be towed or use a trailer or a dolly for the car you have. If the latter you won’t use the equipment on your RV, just a normal hitch ball. If the former you’ll need to set up your new car for towing. This involves having a base plate added, lights and a braking system. All of which can cost anywhere from $1500 - $4000 depending on whether you can do some of the work yourself. Towing is pretty easy and can be very useful but it’s a serious thing and you need to find a good shop or fellow camper to assist.
