the same goes for sprinters with 4AC's, my first car was also my first sprinter when i turned 17, i knew SFA about cars and "maintenence" and it just wouldnt die, in 3 years it only had 2 oil changes, and went through 1 set of brake pads, and a battery!! and i think the car is still driving around newcastle somewhere. The moral of this story is there is not enough power in a 4ac to create stress on any of the parts, and i did delivery driving in it for 3 years, so it was pushed hard...
