I don't know much about this model but I know that it's a Mitsubishi 4 cylider (diesel) with about 135+ HP (I say plus because of the added 3" exhaust) so depending on gearing it will be slow on the high way. With proper maintenance it should last well over 750k maybe more, but diesels cost a lot to maintain. The fact that it has a new clutch at 70k isn't promising and I'd want to know why and what was it's life before it was built out to an Overlander. It's a cool rig but you could built a nice 4x4 van for way less and put 25k in your pocket or live the van life and travel for a long time on that extra savings. Just my 2 cents.
