With the line up of cars you mention in your driveway, that town car and that ls seems a bit out of place.
My 2002 has 240 thousand miles on it, it squeak like hell over speed bumps, the CD player was bad when I bought it some years back, ( simple fix aftermarket sounds better and the bass fills the inside lovely )
I've replace all cooling plastic, DCCV, A/c compressor, radiator, window regulator, coils, and all.
I have to say if you take care of the motor and trans this by far one of the best drive trains I have had. When I bought the car it had 104 thousand miles on it.
