^^ this is true if you are content driving an older vehicle. the IS is already almost a 10 year old car. ofcourse you can buy a new 20 year old car and have that same power. this isn't about how to spend money or what car is a better option for the money. this is just stating the costs of boosting an IS300. it is not cheap by any means.

for more info, just go to www.my.is

that site is the bible for IS300s. just about everyone on that site, shops included, will agree at what i've posted.
