In all honesty, I usually do 90 percent of my car repairs myself. I will go to Valvoline for inspections cuz they are super quick. If they recommend any repairs, get the print out from them, walk into a mechanic and just be confident and ask to have just what is needed repaired. A lot of shops will see a person as dollar signs but if you learn some lingo of what needs to be repaired so they don't try to fuck you over. No the cabin air filter doesn't need to be replaced, same as the engine air filter, unless it's eaten to shit from mice. Get repaired exactly what needs to be repaired, nothing more.
