Pre-purchase walkaround
2015 Mercedes-Benz G63 AMG (W463)
35,000 miles · asking $53,000
Five-year cost to own, maintenance and fuel
~$31,500
A hand-built, body-on-frame luxury SUV with an AMG twin-turbo V8 bolted into a chassis that dates back decades. Ownership money goes into the powertrain electronics, twin-turbo plumbing, aging body seals, and the three locking differentials that most owners never actually use but still have to maintain.

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 35,000 miles.
Door seals and rain leaks$350-$1,250 if not done
0typical window 30k-120k · this car: 35k, inside the window150k mi
The G-Wagen's boxy body and old-school door design mean the rubber seals wear and let in wind and water, especially around the doors and rear hatch. Wind roar at speed, water in footwells or trunk, musty smell.
Turbo and engine oil leaks$1,300-$3,080 if not done
0typical window 40k-100k · this car: 35k, ahead of it150k mi
The M157 is known for leaks at the turbo oil lines, valve cover gaskets, and the front timing cover as it ages. Heat cycling around the hot-vee turbos accelerates seal breakdown. Oil smell after driving, drips under the front of the engine, smoke on cold start.

Hand this to your inspector
A $300 inspection against this list is the best money in the whole deal.
01Cold-start the engine and watch for smoke, then check the front of the block and turbo lines for wet oil.
02Cycle all three diff locks (center first) on level ground and confirm dash lights engage and clear cleanly.
03Drive at steady highway speed and feel for driveline vibration or shudder, then again under hard acceleration.
04Pull back door and rear hatch seals, check for cracking, and look for water staining in footwells and cargo area.
