This has been the best vehicle I have ever owned.It has only been back to the dealer twice,once to clean the throttle body, second to replace the power steering pump. It has almost 80000 miles on it and averages over 18mpg on the road with the 4.7eng. I have a K&N air filter in it and use Mobil 1 5w-30 oil that I change every 10,000 miles. My wife loves the Durango. We have no intentions of selling it.
I think the engine has plenty of snap. It rides great for the type of vehicle it is. The storage capicity is exceptional. The Infinity sound system is great. The power driver's seat is very comfortable.
The suspension could be improved as it wants to fishtail slightly when it gets on a series of washboard bumps.
