Just a quick glance here gives me:

Front rotors: $50 x 2 = $100
Front pads: $55
Rear rotors: $30 x 2 = $60
Rear pads: $35
----------------------
Total: $250, not including sensors or minor bits.


A few months ago I priced out brake parts for my car, and the parts were about 20 percent more. I ended up buying the pads from the dealer, and they were Textar pads with the MB star on it. Just this weekend, I did the rear brakes on my parent's 300E, and ended up using aftermarket Textar pads with Balo rotors. Thus far, the quality seems pretty similar to the pads I bought with the star on it.

I think the key to buying aftermarket is knowing the quality of the brand, that's the only way to make a cost-benefit analysis. Based on people's experiences, I think the aftermarket Textar/Balo combo is probably close enough to MB specs that I'll be using it in the future.
