Retirement - looking for savings ideas

Little known secret is your SS is weighted towards your last 3 years income before retirement. So we threw most of the income on my wifes and she retired first, I'll probably work til 66 and a few months. It will make over a $500/month difference on what we draw. They say got into retirement with minimal debt and a reliable car. Good luck! BTW agree on finish the car! Looks great.
