Selling 2007 cx-7 Need help!
 

I have some doubts about my car after reading about these VVT issues, my car makes a ticking sound whenever I'm stopped at light and has some sort of sluggish wave sound. I thought my car was in pretty good shape until I read about people experiencing the same issues as me. It's 80k miles with some paint chips on the front and back bumper and a reflecter light on the back is busted. How much would it cost to repair these issues and would repairing them before selling really give me my money I'm putting into it after selling it? I'm wanting to ask 7k for it. Thank you everyone! Hope to get some good insight.
