Not that critical yet. I've found that once you talk to someone, then they try to sell. I inquired last year about an O-470 to a different shop for a different airplane. Traded some emails to get a cost estimate. 3 months later he calls and says my engine is ready. Never ordered one, just getting estimates.Umm...
I hate to have to ask, but did you call THEM and ask if they're still in business???
..as permanently closed. I'd call Columbia:they do show up in GoogleMaps
