Curious if anybody on the forum has a high mileage C63S. If so how’s it treated you? Are these cars “reliable”? How long and where can we expect to run these cars up to? Haven’t heard much about the M177 and would love to learn

I modified it to Stage 2, cat DP,CAI and daily drive it hard. Has 90,000 on it now and no issues

love to hear it. I’m stock and planning on throwing on catless dps and stage 2 it soon. how much did it cost you total to install catless dps and tune stage 2? ECU and TCU?
