Use a hairdryer to heat up the glue holding the emblems on. They'll peal off like melted butter.<br> Then, use some bug-n-tar remover to get off the remaining goop.
on one of my services, i just asked the dealer to take mine off. they use a heat gun to remove it and the'll also buff it out for you. looks great! but a lot of people assume its a c240 and not the c320.................and they would be right! ;) still looks good.
