So out of curiousity what did you get? I am in the same situation you are, drive a ton of miles. CPO is by far the best choice, and there are always cars out there to get with the specs you want. CPO is great because you get a car for cheaper with better warranty, so win-win for you. Given that you will drive 100K miles, just drive them all and pick which one you like best. After 100k they are all worth the same -- next to nothing -- so drive what you like. Any of the cars you listed are fantastic, so you are fortunate to have such an amazing decision to make.

I live in the midwest, so I have a BMW X5 for winters and family, and a CPO Panamera for whenever. I was extremely lucky to find a Panamera GTS with only 300 miles that the dealer CPO'd, so I am in heaven for the next 100K miles.
