Mileage is around 231K. I love driving this vehicle. I would like to replace the old shocks and suspension, etc as that is about the only thing I don't like, the bumpy ride. Are there any do's and don't relating to increasing, or decreasing it's value? I wan't to be able to filp this beauty if things get worse financially for me down the road. Should I go old school OEM shocks? Or upgrade for not only for performance but increase desirability on the sales market? Any tips appreciated. Thanks!
