car trailer advice

Ive been looking for a car trailer that once my car is completed I will be able to haul it to the drags a few times a year. Currently I have a trailer that is approx 13' x 6'. I use it to haul my lawn equipment; tractor with bagger, areator, thatcher, and in the winter my tractor with snowblower. It is a single axle with no electric brakes. Works good but is not the right thing for hauling a car although I have used it to haul the Dart once before. I am not looking for the cadillac of trailers as I said it will only be used a few times a year to haul the car. I really was not looking for a wooden deck trailer but because of how slick they can be when wet. Also I am seeing open trailers that range anywhere from 16'to 20'. Question is what is the shortest trailer I can use to haul my car and what width do I need to be able to open my door once loaded. Do I need brakes on both axles and do they need to be electric or one operated with a master cylinder on the trailer itself. Not real concerned about a tool box on the trailer since I will be using a truck to pull with. I know I will need a wench. what else should I look for and what kind of money should I look to spend. I am looking at used as a new one would be over kill since it will sit most of its life. I am not in a hurry as the car wont be running until late this fall. By the way I am located in York Pa if you know of anything close! Thanks in advance for your suggestions.
