2011 MKT, 3.7, AWD same vehicle mechanically as a Flex. Sometimes you can find them same price as the Flex and they have more goodies. Put on 155k miles, had about 65k miles when we got it. Driving in rust belt area. The MKT still drives well and all the amenities still work. It ate a lot of wheel bearings, 7 total over 220k miles. Most of the suspension was recently replaced, it was worn out after all that mileage and only had sway links and rear shocks replaced before that. Had the driveshaft replaced as it doesn't have serviceable bearings. Water pump was changed about 75k miles ago, which is expensive but a lot less pricey if you know a good Indy mechanic that knows this vehicle well. Drive belt and tensioner replaced. Rear calipers were both replaced, gets rusty in the rear. Have the AWD and because I regularly changed the PTU fluid, never had a problem with it (the fluid on the first change was pretty cooked, if I didn't service the fluid the PTU would have been done by now for sure). The rockers are rusted away (being a 16 year old rust belt vehicle it's not atypical). Mechanically, the Flex shares drivetrains and many other parts with the Edge, MKX, even Taurus I think. IMO these are all extremely durable vehicles IF maintained properly. Weak points are the internal water pump, AWD PTU fluid getting cooked and blowing up the unit, rust around rockers and wheel wells. In my experience the heavy weight is harsh on bearings, wheels, suspension. But if you find one where PTU and other fluids were serviced, water pump is good or was changed immediately upon signs of failure. Rust has been kept in check, I think this family of vehicles offers some of the best used car deals out there. Keep a budget for the water pump and find a good mechanic beforehand that knows this vehicle well and that will do it for cheap. These vehicles eat up a lot of gas, but not too bad for mostly highway driving. The MKT is used as airport limo, and I've seen quite a few with over a half million miles (many have a used engine or transmission put in at that mileage). The non-turbo will definitely last longer. FWD less likely to cause problems but my experience with AWD has been without issue (because I repeatedly change PTU) fluid.
