I agree as well, but for different reasons. Saving money is always a plus, but more important to me... I consider the original owner as my "beta testor".
Like my tag "If it were easy I would do it myself". I look for 1 year olds that someone else has already taken care of any warranty work that was needed. With that, they generally come with other freebie mod's (vent, wheel covers, hoses, sway bars, WDH setup, etc) that are specific to that rig that I would have done myself anyway.
It might seem selfish, but I full time and can't really have long periods of down time in the shop without a "home". I try to be sensitive to the fact that the poor soul either made a mistake in their purchase or just need the cash... and I appreciate them going through all the headaches of a new rig... so I don't generally dicker with them too much over asking prices.
It's worked very well for me other the years. (Knock on wood)
