I typically turn vehicles every couple of years, but my CRD is the most entertaining vehicle I've had in awhile. It meets my needs so well. It has plenty of room, it's comfortable, gets great fuel economy (for an SUV), and is a wonderful conversation piece.
Anything with a diesel engine around here carries a premium price, so if/when I get tired of it, I won't have any issues getting rid of it for a decent price.
I'm planning on keeping it to tow my trailer, explore some dirt roads (nothing extreme...don't have skids...yet!), drive back and forth to work, and perhaps set up a biodiesel processor and make my own fuel.
The parts aren't that hard to find given that the Liberty is a pretty popular vehicle. The tranny is in use in TONS of Hemi pickups. The only unknown is the VM Motori engine, but it's used heavily in Europe in lots of applications. They are even building an engine for Cadillac.
Worse case scenario, I take it over to the Nashville Auto Diesel College (
http://www.nadc.edu/) which is a highly respected institution. I'm sure they would love a good diesel project over there, especially given the rarity of the CRD. I'm sure they have some bright students over there that could fix it right up even if they had to engineer something to get it done. After all, how often do they get a chance to work on a VM Motori engine??
Honestly, I'm more worried about the transmission and transfer case than I am the engine. I'm betting the engine will outlast all the drive components and chassis.
