I opted for a 2010 V8 Mountaineer over a 5th gen Explorer because of the fatal flaw in the design of the front wheel drive versions of the 3.5L engines. They have an internal water pump that has a habit of failing and taking out the entire engine in the process. This engine is in numerous cars and SUVs. I don't expect to see many vehicles with this engine on the road as their mileage racks up. Heck, the cost of replacing the water pump in these engines is $1,500-$2,000 or more depending on the repair shop used. The thing that makes me scratch my head is Ford uses an external pump design for these engines in the F150 and Mustangs. IMO, they could have done the same for the FWD versions. Ford is not alone in this. There are reasons one can buy any number of European luxury models with 80k-100k miles on them for next to nothing. It is because they are just one repair away from being scrapped. Lincoln has several models with electrical gremlins that will nickel and dime an owner to death. This, and the engine issue, is why one can buy a 7-10 year old Lincoln for $5k-$7k with around 100k miles.
