some how i lost the hamsters but i got their ride in two colors, retail red and ecofriendly light green. both units came off of thrifty dollar rental leases. 51811 is on this great driving beauty and honestly kia understates the mileage they get. drove this one 109 miles to another sale and it turned in 32mpg combo highway and arlington texas driving. i'm impressed. sorry about the sans hamster deal but life goes on.
