2012 Mercedes Benz 550 4Matic still under warranty

2012 Mercedes-Benz S-Class 4Matic Description

Cost almost 120,000 when new.
Special order colors: Dolomite, Chestnut.
Distronic Cruise, night vision, lane detection, blind spot detection, sport package, Haromon Kardan, etc. etc. I believe this car has most every option, except for the back seats that move and the back seat entertainment. The front seats do EVERYTHING!
I am second owner, having purchased it off lease. The mention, above, of 4 owners is not correct in my opinion. The other two owners might be the Mercedes Benz Corp. of America, and the auto brokerage from which I purchased the car.
I have driven it about 4000 miles in two years.
I have had it completely serviced, regardless of low miles.
I paid almost 2000 dollars for clear bra on front and vulnerable areas
I paid almost 5000 dollars for an extended, transferable warranty that has about three years left and up to about 90,000 miles. Car currently has about 48,000 miles. I have never used the warranty. Car has had no issues whatsoever, but I felt for such a complex machine it was a good idea to have the warranty.
The car is in Seattle. Always garaged, of course. Always pampered and kept spotlessly clean.
Only negative is wheel rash....fixable, but I have not have had it done because it would probably just happen again....part of the joy of having 19 inch wheels.
I would like to keep this car for a long time, but financial pressures are causing me to attempt a sale.
