the tow at under 35 mph is with the engine off.. with the engine running you can go 55-60 mph.
the reason for not towing four down with front wheel drives. is that the steering is slower to react than a rear drive vehicle. which will cause more tire scrub...
the best method is to tow, is by using a trailer. saves lots of wear and tear on drive line and steering components and you won't need to buy a brake buddy...
the next best method is using a tow dolly, great for front wheel drive vehicles. nothing more to buy.. unless you are towing a large vehicle. then you will need brakes on the dolly or something like a brake buddy in the vehicle. also using a tow dolly the rear shocks will wear out prematurely.
