Isn't Jeep starting production of a small diesel Wrangler for the US market?
I can tell you if this were the case, you'd suddenly see thousands of used yj, TJ and jks up for sale. Jeep guys have been praying for this since jeeps were invented, and most would sell a kidney for one, including me.
Also will say I don't mind having lots of money tied up in a vehicle provided it has decent resale value... Current top picks are a Tacoma, a silverado and the wrx. They each have their strengths and weaknesses. A diesel sounds nice, but as you guys have mentioned here, it doesn't make sense for what I want to do with it, as much fun as it would be!
Thanks for all the info guys!
