Re: Purchase Advice Requested - V6 vs. ecodiesel
You said you were looking at a 2014 diesel. Many of them have had problems with the emissions equipment in the exhaust. Seems like most have been fixed but if you happen to find a used one with low miles there's a chance it hasn't been fixed yet. The fix is an updated design for the cat with corresponding software update, I believe. The 2015's haven't had any problems with this because they all have the better hardware already. Something to think about and check on if you find a 2014.
Also have to factor in fuel filter changes every 30k miles and adding DEF exhaust fluid, About $12 at walmart every 5k miles. I easily get 29 mpg highway and even when stuck in stop and go traffic on rt 3, 93, 495, it still easily stays above 20. In fact my ave. mileage has actually gone up sometimes while creeping along in traffic. Diesel's are great...
