I have a C280, and I drive it very hard. I floor it often, accelerate fast, brake hard (when needed!), put the shifter into selective gears and sometimes hold it there at high RPM. I know all this is not necessarily good for my car, but is it bad for it? I am an acid oil changer; I change it between 2 and 3 thou miles. HOw hard is this on the transmission? I plan on having this car for a few more years, until about 175 thousand miles. Will I for sure blow my transmission by then? I also change the trans fluid between 20 and 25 thou miles, or whenever it gets more than a little discolored. Should I mellow out a little? Or can my car handle it as long as it's meticulously maintained? Thanks for the help guys.
