L-Sportline is a factory option in partnership with another company (I forgot the name lol). That company doesn't exist anymore so all the parts are discontinued and very hard to find. The GS's also had an L-Sportline option. It's kind of like Nismo but nowhere near as legendary or performance oriented lmao. Mostly body kits, wheels, exhaust, and maybe springs/struts.May I ask a very new question here? Is L-sport line a company from back in the day and these are the aero kits offered? Or was the L-sport line a factory option that came equipped with different bumpers?
