I am in the process of purchasing a 2014 4Matic C300 Luxury with 21,000 miles. The manufacturers warranty is in force for one more year but the Dealership will be presenting me with extended warranty options tomorrow. The Dealership is not Mercedes. Its a small one that always has great cars. I've bought a car from them before.
Can anyone fill me in on how I should proceed with this? What warranty is good, which is not so good and what is the normal cost?
Thanks for your advice in advance.

If the car is being bought from a non Mercedes dealership do not take their warranty offer. You as a second owner can take this car and extend the OEM warranty for a few more years at a better price from sellers on this site and it covers more/less dealer payment hassle.

I'm interested in extended warranty as well. I have a similar car, same model and year, with similar milage. How to get in touch with some of the sellers mentioned above?

Thank you. I searched, but that thread did not come up.
