You could fly n ride or trailer. We need more RX3's in Colorado!!!
Got our second RX3 that way. The trip back from AZ take the back roads, US 160 thru Bayfield, Pagosa, Wolf Creek Pass, then up 285 from Center or Monte Vista Or cut over from Farminton NM on hwy 64 thru Chama and up thru Alamosa, assuming you're in the Denver area. Weather has been decent lately so its doable even this time of year.
