I am looking for an early to mid 2000 burban. Is there specific year to avoid? What years had the notorious "piston slap" motors? I would not be apposed to the last of the 5.7 vortechs since these were pretty reliable form what I have read so far.. I don't mind high mileage as long as its not 200,000. It needs to be a reliable road capable vehicle. Anyone willing to give me a rundown I would greatly appreciate it.
