i dont know if this has been built into GT3 but if i use my cars for say 5000+ would i see a decrease in performance in relation to the brand new car ? .... or does it stay the same peformance wise as long as i change the oil and do a clean car wash ?
Yup. It ends up being about 2% off of full power. And this is well covered in those big red Read This: threads at the top. They're there for a reason, folks.
