I am the original owner of a 35th anniversary 350z roadster. I have added cold air intake , plenum spacer, dual catback exhaust, underdrive pulley and complete replacement LED lighting system. The stereo system has been completely replaced now with navigation, bluetooth and backup camera. I have recently gotten into ceramic coatings after learning how to get a fine polish on the black paint. The car is show worthy and is driven daily with internals unmarred, unscored and ready for another 190k miles. It's a daily driver and has no troubles reaching high speed of 100-110 mph.
