I guess that's a matter of personal priorities. I'd want my DD to be fun to drive so I don't hate my life (ask me how I know, getting passed by minivans on hills on the way to work) driving to and from work every day trying to save money to fix up my project. Then you have to make a special effort to go out and drive your project [pointlessly] on the weekends. I guess for me that's why a truck is a good second vehicle, as I can still DD it if the 626 goes down, or in the winter, and it can haul a lot of junk around with it in my free time.
Oh, I understand where you're coming from... but there is also something to be said about a car that you don't **** with, and can just drive it. In my old age, I'm beginning to enjoy that more and more.
