When I looked at the photo the first words out my mouth were.oh fuuck

Dude my 1989 corvette still has the factory brake fluid in it and it’s still clean and good fluid.unless you live in smog city or down a dirt road you probably didn’t need the cabin air filter or the engine air filter unless they were actually bad Wich depends on where you live.I live out in the country on paved roads so air filters last a long time out here.and I’m sceptical on the cvt fluid as that should be every 50-75k far as I’m aware although that number may be out dated.I think you got rung for all you were worth.that air filter is like 10$ and the engine air filter 15$I wouldent have fucked with the cvt or brake fluid unless it was dirty or had water in it
