Growing up, we had a Plymouth Voyager minivan that we called "the buggy". As in, "you all get your stuff in the buggy, we're going to town." It rocked. When we finally got rid of it, the third seat was missing and the top speed going down hill was about 45.
Now, my Blazer is ready to be replaced. Even though I've had the Blazer for the same amount of time that I had the Frog (green '97 Chevy Silverado), I never got all that attached to it (hence, no name for it), so I'm ready to see it go.
To replace the Blazer, we are getting a Land Rover LR3. It rocks. I think there is a possiblility that, given enough time, it may even come close to being as great as the Frog. Anyway, it is kind of a family wagon type of an SUV, so I'm going to call it "the buggy."
