Yea it is a shame about dealing 21.
Dealing 21 is the only job I've ever known where you can work an entire shift with your fly undone (they wear aprons).
About you car
A lot of collisions cause the piston rings to score the cylinder walls. Didn't you say you now hear pinging under the hood?
BTW - Did you get whip lash from the rear ending?
A girl friend and I both had whip lash from a rear ender that totalled my 62 Chevy. Our necks hurt and were swollen.
I lost my babe mobile and my date that night, and all I got was a hickey. (^%&$)
