how much abuse can these cars take? cause last night i was having to follow a bunch of people through rush hour in the city and i kinda had to red line it a few times to catch up and spin the tires on take off (first time and i didn't even know my car could do it lol) and then on my way home my transmission started to act a little strange and my engine began to make a new noise...its a 06 Sebring with the 4 cyl. so i know its not the age...but how much abuse can these things take?
