I love my ecodiesel Grand Cherokee (2014). Nearing 100k miles. It's a fuel economy diesel, NOT a "tow the world" diesel. Long as you remember that (I tow with my Cummins), you'll love it. My Grand gives me mid-high 20s commuting in the mountains and low 30s on highway trips. 5,500#, AWD, Summit trim with ALL the luxury fixin's. Dollars per gallon are higher, yes, but dollars-per-mile? Definitely lower. I know, I track my fuel use because I have company vehicles / tax deductions / etc.
Maintenance? Bah. Fill for life HP8 transmission, no maintenance needed. Oil change every 10k. Fuel filter every 20k. Fuel in tank, DEF in tank (I fill mine once a year, to the tune of about $17...woo. hoo.), air in tires, filters when they're dirty, brakes when needed....and drive. No tuneups, no spark plugs, no coils...easy peasy.
The engine is a tank, too - six bolt (!) main girdle bottom end, compact turbocharger, and plenty of performance headroom - look up the Banks Engineering 630T to see what they're doing with it. It's a serious motor.
In nearly 100k miles, I've had 2 EGR cooler replacements under warranty; a leaking steering rack under warranty; a wheel bearing under warranty....and that's all. I have a list of diesel stations I use that have good fuel...and I just drive it. Starts like a gasser, quiet like a gasser, runs like a gasser, 6k redline like a gasser...but a hell of a lot better fuel economy than a gasser (and no repeated lifter replacements like the pentastar V6!).
As for current pricing...get used to it. Not just cars, but everything. Inflation. And, low supply levels overall. Those two add up to high demand, which results in high prices. Rates going up have started to end the "it'll be that much for it; do you want it or does it go to the guy behind you?" situations, but...demand still outstrips supply, and with the dollar worth less and less every day...well...everything costs more dollars now.
