Pre-purchase walkaround
2022 Porsche 911 (992)
670 miles · asking $502,911
Five-year cost to own, maintenance and fuel
~$20,300
The 992-generation 911 is Porsche's current turbocharged flat-six sports car, sharing much of its platform across Carrera, Turbo, and GT variants. It is a relatively young and reliable platform, but ownership money goes to consumables (tires, brakes), PDK service, and the usual expensive-when-out-of-warranty electronics and coating repairs.

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 670 miles.
PDK transmission fluid and mechatronics service$2,310-$6,990 if not done
0typical window 40k-100k · this car: 1k, ahead of it150k mi
The 8-speed PDK requires scheduled fluid service, and neglected units can develop clutch and mechatronic wear. Harsh or hesitant shifts, or overdue service history.
Direct injection carbon buildup$350-$1,250 if not done
0typical window 60k-120k · this car: 1k, ahead of it150k mi
Direct-injected engines can accumulate intake valve carbon since fuel does not wash the valves; mostly a higher-mileage concern. Rough cold idle or slight misfire at higher mileage.
High consumable wear (tires, brakes, PCCB)priced only if found
Condition-driven, not mileage-driven, so it is not in the totals and inspection is the only answer. Worn staggered tires, low brake pads, or discs near replacement.

Hand this to your inspector
A $300 inspection against this list is the best money in the whole deal.
01Confirm PDK service history and check for harsh or delayed shifts on a test drive
02Cycle the front axle lift (if equipped) fully up and down, listening for slow operation or faults
03Run a full PIWIS or dealer scan for stored fault codes and pending software campaigns
04Inspect tires for staggered wear, matched brands, and DOT date codes on all four corners
