Hello - My Honda CR-V is a 2006 LX model. It has about 145000 miles on it. I no longer have a comfortable driving feeling when I drive the car. It just feels too bumpy, noisy and is not comfortable over a long distance. Instead of spending money investing in a new car, is there something I can do to make the ride smoother (e.g. new shocks)? Also the central locking does not work, and interior cabin lights don't turn on when closed or open and the rear door open light is always on despite it remaining closed. Are these lighting issues something I can work on myself or do I need a mechanic?
