I would say a motor home mounted tow bar. Your car is pretty light so mounting a tow bar on MH will decrease the load on the front suspension of the toad. I prefer Roadmaster equipment, but any of the major builders will work. You can do a search oninternet to find very good used ones.
Think about your lights. I have used different types over the years. Magnetic, auxilary lights and hardwired. Over time I have found hardwired properly installed is best for us.
If you decide to install an auxilary braking system, get one that can stay in place. SMI Stay-N-Play or the Roadmaster Invisibrake. You would just need to turn on a switch. No components to move in and out of driver's area.
