Mean or just careful?
A set of OEM front pads for my 190E cost about 12 pounds ($18) and the discs (rotors) about 7 pounds ($11) each. It takes me about 20 minutes to change the pads.
I think that is excellent value for money, and I don't worry that I get 10k out of my pads.
If you guys are getting 25k out of your pads, then you must use a lot of long straight roads!
