Im going to have to agree with never buying a modified car (besides one thats lowered/rims) otherwise you know that the person that owned it drove it harder then a stock car would be driven. There is a reason people modify there car for handling, and i wouldnt think for a second that person babied the car. Even tho they did routine maintenace on the car, it can still be in poor shape due to hard driving. I mean, slotted brakes practicly scream " Im driving extremely fast in my car, i need to stop harder "
