Assuming it's well kept, like new garage baby, driven regularly etc, my first reaction is its for sale in CO where weeds legal cause they're high!
But they used diesel market is so far out of wack right now, not even funny and a perfect as new LLY Dmax is only half a step away from the highest regarded pre dpf diesel trucks out there and IMO is almost as good and as refined as any new truck out there.
Late LLY trucks had no big issues I know of. Early ones had a couple things that aren't horrible to remedy.
I personally wouldn't spend that much on that truck but someone may spend close to that. I wouldn't give 30 for it but many would and based on the current market, it will sell for that without much issue.
If $30k ish is the top of your budget and you don't care about warranty or having a truck that is a couple generations behind the current models, then it is not a ripoff at 30.
