I understand that value has different meanings to different people, but the space utility, design, quality of vehicle, and comfort is unparalleled for the money. I bought mine slightly used (it has 1800 miles on it in the same model year) and I use it as my daily driver as well as for many of my family's long trips and it handles the interstate and in-town driving well. The seats fit me well, though, they are smaller than some, and there is plenty of leg and head room for my 6'2" frame. If I had to replace it tomorrow, I would try to replace it with another PT.
Cargo flexibility. I have used the cargo bay with many different seat configurations. We were able to easily fit a diaper changing table in the back with the seats tumbled forward. Flexibility is excellent.
I wish there was a little better gas mileage, but I will give that up for a better feeling vehicle, as it feels more solid to me than others.
