for a bimmer, front and back, rotors and pad, i would say 1100ish is around in-line for a dealership.
rotors are like 150 a piece, pads are 100+ for each axle, so roughly 4 hour book time, and it's 1000 easy. at a dealer.
so i can see your point there, HS.
for Rio, though.. that seems little excessive, unless they were replacing all the calipers too.
me, of course, i do it myself for 500. just the parts.
