Cars have been rear wheel drive for over 100 years(your father probably learn to drive in RWD)and yes you have to do certain things to drive in thesnow BUT you do some of the same thingsin FWD cars.I put my tool box in the trunk,make sureI have good tires,wipers,etc,no problem.DRIVE SAFELY!!Even 4wds skid andget stuck.Personaly,I think most people cant tell the differance between themin most driving siturations.I have been driving 44 years and have screwed-up in both. PS -- Get ABS/TRACTION CONTROL and use it.

 

Every rear wheel drive car I get, I buy a set of studded tires and extra rims just for the winter.
When winter comes, I put on the studded tires anda little weight in the trunk.
You should be able to get some rims that match the mustang for not too much

 

front wheel drive cars dont do anything better than rear wheel drives. Picture when your on a hill trying to chug up it but wait I have front wheel drive, and all my weight is down hill....to the rear wheels eh hem.....Theres other things, I have to ask my dad, hes the expert on that fight.
