Kia Rio
Says Matt DeLorenzo of Kelley Blue Book: "If you want the utility of a sport/utility, look at hatchbacks."

Hatchbacks are less expensive than compact SUVs to begin with, and as they are in less demand than crossover SUVs, they are a better deal for the buyer. A brand new Kia Rio has a base price of just $15,390; 2016 models now cost about a third less than that.
Volkswagen Jetta
DeLorenzo said that a warranty from VW "has six years (and) 72,000 miles," making these great used cars in terms of extended coverage. A new Volkswagen Jetta costs $18,745 today, while a 2016 Jetta can be had for less than $12,000. And US News gave the 2016 Jetta a nine out of 10 score for Total Cost of Ownership.
Subaru Crosstrek
The capable, compact Crosstrek underwent a redesign in 2018, which makes earlier models even more affordable than they would have been. A brand new Crosstrek has a base MSRP of $21,895, while according to Kelley Blue Book, 2016 year option has a fair purchase price of $16,662.
Kia Soul
If you want a pre-owned car that's quite affordable now and you're not worried about re-re-sale price later, consider what DeLorenzo calls a "trendy, odd-ball vehicle" like the Nissan Cube or the Kia Soul.
As long as you plan "to hang onto it for a long time, they're cheap but don't have much in retained value," he said. A three-year-old Kia Soul can be had for well under $12,000.

Ford Focus Electric
A 2016 Ford Focus Electric can be found for between $13,000 and $14,000 if you shop a bit.
And as DeLorenzo explains, "If you're an urban dweller and have access to a garage with a plug, you might also check out a used EV. The prices are really low, and while many of them have less than 100-mile ranges, if you just need a town car, it's a perfect option."
