I recently purchased a 2011 Honda CRV EX-L, the vehicle was well maintained by its two previous owners according to the maintenance records, that came with the vehicle. The vehicle currently has 70k miles and athough I am not having any issues with it. I'd like to know when the struts should be replaced and when I should consider tuning up the engine. As I said before, I am not having any issues. I'd appreciate your answers and thank you in advance.
