OK, I bought the 2011 MKX earlier this year, and so far I like it, and plan to keep it for maybe at least 4-5 years. I'm thinking about the Lincoln Maintenance Protection Plan (LMPP), is it worthy? My dealer quote me $200 off from the regular price, so here's the price I will get:
3 yr/60 K - 800
4 yr/80 K - 1,275
5 yr/100 K - 1,460
I usually won't consider anything dealer offer, but i know if I bring the MKX back to dealer for service it might be quote pricy. What do you guys think? Can anyone do the math for me? Any MKX owner bought it?

Well if you know your driving patterns it should be pretty simply to estimate what you'll spend on maintenance over the life of the plan. Find out the retail price of the required services (oli changes, inspection rotation etc)
These are the only wear parts covered:
• Brake pads and linings
• Brake rotors
• Light bulbs (excluding headlamps)- non headlight bulbs are cheap and easy to replace
• Shock absorbers- These should not wear out. They should easily last the 4-5 years you own the vehicle if they fail they likely will be under warranty
• Clutch disc -Not applicable with MKX
• Spark plugs -Required at 160 ,000km So NONE of those plans actually cover plugs based on a normal maintenance schedule
• Engine belts and hoses - See above belts are not recommended to be replaced before 160,000
• Wiper blade- Not sure if the MKX requires special blades. If so that can be pricey. If you can replace your own blades then you might go though a set a year or so.
Basically you need to do the math keeping in mind some of the wear items that are "irrelevant" like plugs but also the many "filters" the MKX requires I count 2 cabin air filters
