I have a couple cigarette holes in my Celica due to my mistakes earlier and my friends' stupidity. Smoking anything with an ash/ember was never an issue if you followed the rules.
#1 don't burn a whole in my car.
#2 don't let back ash fly into my car/don't ash in my f***ing car
#3 (Celica only) you burn you dispose personally. What you take in you certainly take out (Like a National Park).
#4 A Slob that doesn't follow #1-#3 gets the shaft. Which is:
#5 A new meaning to the word "barbeque".
Also no matter what car, type, year, quality, price paid, etc. the rule was never burn a hole in the seats. You might as well replace them if it bothers you that much. I have 2 in my floor and 1 on the headliner for my stupid self and my friends at the time. Those can be covered up or unnoticed and they are. But the seats...
