How long have you owned the car? How do you know that the person that owned it before you didn't take it off-road and jump it a few feet in the air, then land and tweaked the unit-body, causing misalignment with the doors and resulting leeks? Do the doors line up nice and open and close easily? Are they hard to close or do they bind when they close? I've seen crazier things happen.
Case in point - Toyota Avalon, maybe a 2003 or 2004, had the passenger side lower ball joint ripped off the control arm. It didn't separate, the whole ball joint assembly was sheered off the lower control arm. The owner'* son was driving the car and said he was turning around and "it looks like a bolt came loose." Can you say curb? Only three small rivits between the ball joint and the control arm, and the ball joint isn't even set in the control arm, it just attaches to the control arm. What was the cause? Shotty construction that was weak and broke, or abusive driving? Or both?
My point is that cars will be abused, then sold, and problems will come up in the future.
I know this guy with an 1999 Oldsmobile Aurora that has taken such a beating (from him), I can't imagine that it still runs and drives. One of his favorite things to do is let his pass. side wheel slide about a foot into grass in neighborhoods without curbs and gun it, resulting in an ultimate one-wheel-winder. Luckily he'* got a 4T80E, or else his diff would have blown long ago. He like to travel 20 mph over the speed limit, and, needless to say, he'* got a lead foot and his car sees 5K rpm under normal driving and normal aceleration. Heavy cornering and heavy braking are also normal. Curbs aren't an obsticle for him, and where the pavement ends, he keeps going as grass and mud are fine substitutes. I wouldn't buy that car for $10, but at some point someone will buy it used, and it'll give them nothing but trouble, and they'll blame it one the car bing a piece of crap, not realizing it'* history.
Just food for thought.
