So, I went to a web site, mpgomatic.com and compared my 08 Vert MPG to other verts. Below is a list of cars to get the same MPG/. But none of them are as much fun at the PT

(well, maybe the Crossfire is, but you can't put grandkids in the back)
The other thing that is cool is that you can compare one car (old car) to another (new car). Using my PT as the "old car" I could see that had I gotten a Prius (at 42 mpg), I would have saved about $6200 over the first 100,000 miles. However, the Prius costs a lot more than that as compared to the PT.
Just another way of justifying the PT Vert.
