The only problem it ever had was that the fuel gauge was broken, so I would never know how much fuel was in it, and so sometimes it would stop in the street.
The windshield was amatuerly replaced, so it would slide down, and rain would come in through the top, and it cracked shortly before I sold it.
It smelled like mold about 4 months later due to the leak.
Radio, A/C never worked.
Front end looked damaged.
The body was covered in little nicks and dents.
The black paint was covered with swirl marks and was faded on the roof.
I purchased it in August 2005 for $550, and when I got it, it looked to me like it hit a wall or something at 15-20MPH, but the only visible imperfections were the missing bumper, loose grille and headlights, and the metal frame under the bumper.
I got it with 95,000 miles, so it ran pretty well, and could pick up speed instantly.
It was adequate, I would say, for comfort.
I sold it in December 2005 for $200, mainly because I got another car, because the windshield cracked.
For the few months I owned it, It did better than what my family expected, nd I would say this was the most reliable of the Fords we owned so far.
Obviously most used Aerostars are probably in better condition than mine, so I would really reccomend one to people, and they also look better than most van of the same time period.
