ok first off you guys are idiots, the is300 bone stock is pretty decent, at least someone on this forum knows that it has a supra engine! I am sorry, you would be an idiot to choose a msp over a is300. Reason one being it can be made into one hell of a sleeper, two you can turbo it, boost, and produce two times what the msp can't do in hp, and three it is a lexus....luxury sport sedan. Why do you people compare cars like this. That is like me saying should i buy a geo or cavalier. Yea, i know that i have an msp and i am happy, but if you had the choice an is300 would be the better decision. Not meaning to flame but our msp's aren't necessarily luxury cars, they are bang for your buck cars.(argh)
