Some 2013 and earlier Honda Fits should be down to $9000 now, since they cost as little as $12,000 new (what I paid for a manual transmission base model in 2012).
CR-Vs are going to be higher, as they are SUVs (so demand is high) and were a lot more expensive than anything else smaller than the Accord. Hondas hold their resale value well in most parts of the country.
If Saturns are difficult to find, most GM compacts and (four cylinder) mid-size cars from about 2010-2011 on back into the 1990s are just as towable as a Saturn: Chevy Cavalier and Cobalt, HHR retro wagon, Malibu; Pontiac Sunfire and G6, Grand Am, some Grand Prix; Olds Alero and some Cutlass; Buick Skylark, and so on. I just found 244 Cavaliers under $5000 asking price, within 200 miles of where I am sitting now (Detroit); the prices might be higher for non-rustbelt cars.
If you want an SUV, Equinox works as well as a Saturn Vue, for towing (the last Vue was a badge-engineered Equinox). At least 60 of those under $5000 within a couple hundred miles of Detroit.
