Who Should Buy Cadillac vs Porsche?
If you want the lower running cost, lean Cadillac and target the XT5, ideally a 2019, which has no recalls on record. Watch for a "Steering Assist is Reduced" warning. Skip the 2021 Escalade because of sudden engine failure. If you want an Escalade, the 2020 is the pick, but know that lifter and camshaft failure can lead to repairs near $15,000.
If you want a Porsche and can accept higher bills, the Boxster is the strongest of its lineup. Look for a 2018 and skip the 2021, which drew seat belt and back over prevention reports. The Macan also rates good. Be careful with the Cayenne, which rates mixed and costs about $1,231 a year to repair. Buy a 2018, avoid the 2019, and be wary of melting charging cables on E-Hybrids and a lurch before a full stop.
The Bottom Line: Cadillac or Porsche?
For most used-car shoppers, Cadillac is the safer pick, and the XT5 is the strongest single model across both lineups. Choose a 2019 for its clean recall record. Expect to pay about $264 less per year to repair a Cadillac, roughly $1,320 over five years. Pick Porsche only if you value its milder complaint record and will choose the model year carefully.
