CONUS car to buy that I may have to sell in a year

Sold both my cars 4 years ago when stationed in Okinawa. Just moved back but there is a good chance I may go overseas again in 10-18 months. I've bought one new Toyota hybrid I'll bring with me and just keep for 15+ years, but I'm not sure where I'm going next,, so the second car for my wife needs to be something that will hold some value and be easy to sell. ie doesn't have to be cheap, just low risk.

The only special caveat is we'd prefer a compact/sub-compaxt SUV, as we live in New Orleans and the flooding and potholes are intense. I've done a ton of research already and I'm just really concerned with the market as it is that the reasonably prices, high mileage cars or barely under MSRP lesser mileage cars are all going to crater in value and I'll have paid $5k+ for a year of a car. Thanks for any help/sanity you can give me!
