Pre-purchase walkaround
2009 Porsche Boxster (987.2)
mileage unknown
Five-year cost to own, maintenance and fuel
~$16,800
The 987.2 is the mid-cycle Boxster refresh that ditched the problematic M96/M97 for the new direct-injection MA1 engine, plus the optional PDK dual-clutch gearbox. It's a genuinely reliable driver's car by Porsche standards, but the money goes into PDK service, cooling and convertible top wear, and the usual German electronics and suspension bushings as they age.

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 180,000 miles.
PDK mechatronic unit and clutch wear$2,310-$6,990 if not done
0typical window 60k-120k · this car: 180k, past it200k mi
The dual-clutch PDK is durable but the mechatronic valve body and clutch packs wear, and skipped fluid service accelerates it. Harsh or delayed shifts, jerky low-speed engagement, or a transmission fault warning.
Water pump and thermostat failure$550-$1,600 if not done
0typical window 50k-100k · this car: 180k, past it200k mi
Plastic-impeller water pumps and thermostats are a known wear item on the MA1 flat-six. Coolant loss, overheating, or coolant smell after drives.

Hand this to your inspector
A $300 inspection against this list is the best money in the whole deal.
01Confirm PDK fluid has been serviced on schedule and test-drive for smooth engagement from a stop and during 2-3 shifts
02Pressure-test the cooling system and inspect the expansion tank and coolant pipe seams for weeping
03Cycle the convertible top fully up and down, listen for hesitation, and check footwell carpet for dampness from clogged drains
04Cold-start the engine and listen for rough idle or stumble that points to HPFP or injector issues
