97 crown vic
Free. Got it when my last car died, someone gave it to me because I bought a couple others cars from him (under 600, the other two). 97k, ran fine, drove the wheel off it, then had the lower a arm rewelded to the frame (200 bucks), and drove it another 2 years to its final resting place. horrible gas milage, sky blue inside (leather) and out, steering wheel was 90 degrees to left to go straight, but still had lots of play at that. Mind you, it was free, and not worth a dime when I got rid of it. So, I honestly got my money's worth of it. avg 12 in the city, 19 on the highway. Just perspective on why I think the MPG was bad: I had two other cars years ago, a 79 lesabre (17city/24hwy) with a 350 v8, and a 85 lesabre (same) with a 302 v8 that got better MPG than this thing with a 4.6 v8!! Really??
But, it was free.
