I'm finally looking at purchasing a WRX to daily over my 17 F150. I came across a 2017 WRX Base 41k miles Subaru Certified. The problem I see is the car had Transmission along with some other components and AC components replaced at 40k miles. Should I be worried that this might be a lemon or should I trust Subaru is going to stand behind their product? Maybe I should just jump on a 2018 for 4k more.
