If you're paranoid about being upside down on your Toyota after 3 years, you're gonna be in a worrrrrrld of pain when you get that BMW or Audi past 30k miles lol.

It sounds like you've made up your mind. Choose a car to lease for 3 years, give it back to the dealer, get that beamer, instant buyer's remorse, sell it back at a fraction you bought it for, and then buy a used Corolla.

Nothing anyone says here will change your mind.
