I vote Diesel
Since I tow an RV around a lot, I vote go for the diesel.
I have an 07 CRD and have had the swirl experience, and replaced on glow plug, and I am about to dig into a turbo actuator issue. That's about it. The swirl fix is easily resolved now. The glow plug cost me $37.00 and 1/2 hour of my labor. I just ordered a turbo actuator for $300.00....we'll see how that goes.
If you have a dealer do repairs....it is big $$$$$$$. They want $7000 parts and labor to replace a turbo and will not do just the actuator.
