What to look for
991.1 GT3 engines
Early cars were recalled and many had engines replaced by Porsche. Check what was done and that the paperwork is with the car.
Over-revs
Manual cars store over-rev history in the engine computer. Read it with a factory scan.
Front lift and PDCC
Check every hydraulic option works; they are costly to fix.
Maintenance schedule

Intervals are whichever comes first, miles or years. "Porsche factory (converted from km)" means Porsche's own figure for another market, turned into miles with the same km-to-mile pairing Porsche uses in the US. Your car's own maintenance booklet is the final word. HBi Auto's recommendations for cars that are tracked, driven hard or stored are being added by our service team.

Written by the 911 Buyers and HBi Auto team in Mocksville, NC. Market numbers come from 911 Tracker's VIN-checked US sales and say what they are based on; maintenance intervals say where each one comes from. This course is general information, not an inspection, an appraisal or legal or tax advice.
