So, let me get this straight ... You feel you deserve to be compensated because you have a slight burn mark on your bum? Please tell me you are only joking about filing a lawsuit ...

Yes, I believe you should try to be wealthy as a result of a burn on your tush. Actually, you should try to become a millionaire because of the red mark! Look at the humiliation and embarrassment you will have to endure for the rest of your natural life because of this red mark. People far and wide will stop their cars in the middle of the street to gawk

as you walk by, because of your horrific disfigurement (on your tush).
Get real. The heating element burned out. It didn't burn your child so never mind imagining it did. Wait a second, it burned your parents child, so YES, YOU SHOULD FILE A LAWSUIT. Whatever you do, don't waste any time. In a week, everything will be back to normal on your once flawless pooper, but you should profit as much as possible. If your interior light burns out, you should file a 2nd lawsuit. What if your child was trying to do her homework on the ride home and can't finish. As a result of the gross negligence of BMW, she will fail the class, then fail the grade, be a pariah in her own school, drop out, have low self-esteem, take drugs, OD, and eventually die all because of a faulty bulb. BMW MUST PAY, AND THEY MUST PAY NOW !!!

Or, you can accept the fact that your out of warranty Bimmer had something fail it, and have it replaced at 1 of 30 places in the largest city in Canada.
Just my $.02 ...
