We've been eyeing up used MX's as well for around 6 months. Some big pricing movements lately. I'm thinking this summer we might see the 90D's constantly below $50K with 4 year warranty's (6 seaters). I'm really curious where the MX '17 100D (six seaters) will land. Very little inventory for those with 4 years warranty. Most seemed to go around $70K mark. I don't think a 20K delta though is worth it. You might save yourself 1 stop and 30 minutes on a 6 hour trip that most do once a year. I'm thinking I'd spend at most $10K more for the extra battery and AP 2.0.. which would be around $60K. Interestingly you can get a fully loaded performance MY w/ 7 seats new for slightly over $60K... with better modern tech and better battery distance/charging rates. I'm guessing this might anchor pricing a bit towards 60K as well. Should be fun to watch!
