hi, I need some help to decide weather to purchase a 2000 dodge ram 1500 magnum or a 2003 dodge ram 1500 small engine. they are around the same price, the 2000 has 109000 miles and it's really clean, tires need to be replaced. the 2003 belongs to a friend, had overheating problems but radiator and pump were replaced, tires and brakes are new, it has 125000 miles.
