Pre-purchase walkaround
2021 Porsche Taycan (J1)
29,000 miles
Five-year cost to own, maintenance and charging
~$7,600
Porsche's first EV, a genuinely great-driving performance sedan let down early on by immature software and electrical gremlins. Ownership money goes into 12V systems, software-triggered failures, and out-of-warranty high-voltage components that are not cheap.

Hand this to your inspector
A $300 inspection against this list is the best money in the whole deal.
01Confirm all recalls, especially the loss-of-drive-power and 12V-related campaigns, are closed with Porsche.
02Verify current software version at a dealer; many early faults are only fixed with the latest firmware.
03Do a full AC and DC charge cycle to confirm the onboard charger and both charge ports work.
04Check battery state-of-health readout via a dealer or Porsche diagnostic tool, not just range display.
