Even tho' it's where I keep my plane, I didn't know they were talking new. I assumed gently used.
Still, from a financial standpoint, it really is hard to argue against a 182. A Saratoga is kind of a blunt instrument -- you don't use it for pattern flying or local jaunts, it's to take families to destinations. As a rental, though, you run up against the typical 3hr min per day, or some such. Hard to see how that makes sense for an FBO, given most such trips would be over weekends.
An Arrow would be cheaper for complex/commercial ops. A 182 would be cheaper for rentals (albeit doing nothing for the commercial training) I ASSUME, given the fixed gear and insurers antipathy towards folding legs. I would bet that insurance reqmts would chase away many folks from the Toga.
For me, I want a Saratoga. Financially, for the FBO, as Ron and many others have said, the 182 probably makes sense. Henning's right -- there aren't many 6 seat rental options in the area. Still, I'm not sure there are many 6 seat RENTERs in the area either. If I fly with the fam, say up to NE, at most in a Saratoga it's a 1.5hr flight. That's one expensive weekend on a 3hr min rental.
Ahh, how about an Arrow AND a Saratoga. Not my money, so I feel good about spending it.
