If you buy a Porsche in the US, buy it in Oregon. They have no sales tax on cars. Title snd registration cost will be about $300 to $400 on any new Porsche.. Carvana should be avoided period. They are known for taking months to deliver titles. CarMax is legit, plus they would ship the car to a Oregon CarMax dealer, just pick a CarMax in Orwgon to buy from.

Good 🤞
