Ford Motor Co. vehicles took four of the top 10 spots in the latest list from Cars.com outlining the steepest used-car price hikes for April.

According to this report written by Mike Hanley of Cars.com, the 2012 to 2014 model-year used car with the biggest increase in asking price last month was the Lincoln MKZ, which had a 3.1-percent increase from April 1 to April 30.

Other vehicles in the Ford family to crack the top 10, according to the Cars.com charts from Paul Dolan, were the Lincoln MKZ Hybrid at No. 6 (up 1.7 percent), Ford Expedition EL at No. 9 (up 1.5 percent) and the Ford Flex at No. 10 (up 1.5 percent).

Conversely, the Nissan Leaf had the biggest used-car price decrease for the second straight month (down 4.7 percent).

“Gas prices aren't driving demand for alternative-fuel cars like the Leaf,” Hanley wrote in the post. “Even though the national average for a gallon of regular has been moving up in recent weeks and now stands around $2.65, according to AAA, it's still about a dollar less than a year ago when the average for a gallon of regular was $3.67.”

Hanley also points out that luxury vehicles accounted for seven of 10 biggest price declines last month, including the No. 2 (Land Rover Range Rover SUV, down 3.3 percent) and No. 3 (Porsche Panamera, down 2.9 percent) spots.

Both top 10 lists can be found in the full report. 

Note: Models eligible for the list had to be from the 2012, 2013 or 2014 model years and have a minimum of 250 units in the Cars.com national search listings.
