Pre-purchase walkaround
2006 BMW M5 (E60)
96,000 miles · asking $15,000
Five-year cost to own, maintenance and fuel
~$29,100
The E60 M5 is a naturally aspirated V10 super-sedan built around a screaming 8250 rpm engine and a temperamental single-clutch SMG gearbox. Ownership money goes almost entirely into keeping the S85 alive: rod bearings, throttle actuators, and the SMG pump are the big three, and none of it is cheap.

What to look for on this one
Every used example of this chassis has the same questions. The bands show when each tends to surface; the gold line is this car at 96,000 miles.
S85 rod bearing wear$3,020-$9,970 if not done
0typical window 40k-100k · this car: 96k, inside the window150k mi
The S85's rod bearings have marginal clearances and wear out from the factory, a well known Achilles heel that ends engines if ignored. Metallic knock on cold start, metal shavings in oil, or catastrophic engine failure with no warning.
SMG hydraulic pump failure$1,100-$2,180 if not done
0typical window 50k-100k · this car: 96k, inside the window150k mi
The single-clutch SMG III system relies on a high pressure pump and accumulator that wear out, leaving the car undriveable when they go. SMG warning lights, car stuck in gear, or refusing to shift.

Hand this to your inspector
A $300 inspection against this list is the best money in the whole deal.
01Pull an oil sample and inspect for metal, and check service records for any rod bearing replacement interval
02Scan all modules and read SMG clutch wear percentage and adaptation values
03Confirm both throttle actuators operate and no reduced power faults are stored
04Cold start the engine and listen carefully for rod knock before it warms up
