I have to do a bunch of business travel for next year or two, probably 150-200 hours a year. Not too keen on riding in a small tube with 40 strangers with unknown COVID status. Mostly regional trips of approx 600 miles, eg from home in Tampa up to coastal areas of NC or MS, with a few longer trips to OH and possibly CO front range. Max load would be me plus one pax and light bags for 1-2 nights. Priorities would be reasonable XC speed, range to go 650-700 miles nonstop, and stable platform for learning IFR. Would like to avoid potential big maintenance hits or pressing upgrades in next year or two, so looking at low time or mid time engines. Need a model that will sell fairly quickly if cash needed for other purposes. Background: I'm 55 y/o and have 300 hours, accumulated over 25 years of sporadic flying. Half of that is tailwheel and a quarter of it is upside down, mostly in a Decathlon. I also have about 100 hours XC in a C182. Always wanted to get an instrument rating but never quite got it done, mostly because I fell in love with taildraggers and acro. With my near vision starting to get worse (normal age related), I feel like it is now or never for the IFR ticket. My budget right now is $60-70K. Am focusing my search on early PA 28R Arrows. I have some time in them and am comfortable flying a retract. Seems to be a reasonable number of those on the market in that range with mid time engines and partial avionics upgrades. Am also looking at C182 and Cherokee 235, though my budget will only barely scrape the bottom of the pool on those. Would also consider a C172, though those are either high priced or have 10K+ hours, or a Cherokee 180 with nicer avionics. I prefer a CS prop. Any other aircraft that I should be looking at? Older Mooneys are in my range, but my impression is those are less forgiving for training. Love a Bonanza but that is probably overkill for my mission, and out of my price range except for a few of the very oldest planes. C177/177RG, and 172RG are possible, but there seem to be very few on the market. I don't have a lot of knowledge on avionics packages optimized for IFR. Seems like a lot of the older birds have INOP autopilots, and that would be bad for a student instrument pilot, especially one who is juggling reading glasses. Also seems like I should prefer GPS WAAS over old school systems like NDB, DME, etc. Finally, some of the nicer arrows are on the west coast, so I might have to do a distance buy. Any tips on that, such as finding an unbiased inspector for a pre-buy? TIA for any wisdom you wish to share.
