Help me understand these mods

Me again, the old lady who still wants to be in the cool kids club. I'm looking at a 2019 with 79k miles. Seller says he added the following - anything to be wary of here? Also, what do we think of 16.5k for the price? Looks clean.

-KTuner V2
-MAperformance cold air intake
-Perrin motor mount inserts
-Acuity shifter cable bushings/spring
