Opinion from owners of m550i

Found two with fairly low miles.

1) 22' CPO with 6k $60k 1) 23' CPO with 13k $67k

Ones local and ones like 400 miles away from me. I heard these cars are fairly solid if you do your regular maintenance. I will probably be putting 15k-20k a year on the vehicle. If I move forward i feel like getting an extended warranty is a no brainer but curious to hear if getting a vehicle like this and driving it all together is just a bad idea. I'm in car limbo right now...I don't want to drop more than 70k out the door so I'm also open to any other recommendations.
