In my camaro and a friends firebird if we put our keys to accessory and push up slowly to lock we can pull the key out with the radio playing still. but... ther eis a few second delay from when they key is removed to the radio re-engaging. the problem is that i came home from college yesterday at about 3 and went to my house. this morning when i went to start my car i sat in it and i heard my faint radio going. i put th ekey in and sure enough i left my radio/subs on all day and night. drained my battery and i had to have my friend wake up and drive me to college lol. i just want you all to be careful not to do this if you can do this little "trick" as well.
