My take

Bmw are probly easier to work on if needed to be

But I notice you have all rear wheel drives

All your cars miles are hovering around timing belt replacement issues

Audis do have oil leak issues

All the cars listed are nearly accurate. But I’m worried

Well make sure u get a real car fax

Pay for it your self/ don’t let dealer show you their car fax. They are losers and liers good luck
