Happy Easter, I have a question

My husband and I don’t have credit card debt but are trying to build our savings account up. We live paycheck to paycheck and have no big savings and only a small college fund for our son (he’s almost 6). My question is do you have any tips for saving without giving up your car payments? I know Dave really stresses to buy something you can pay cash for but my hubby says we are not getting rid of our cars. I have a 3+yo van and he has a 1 yo truck. He’s willing to bend other places but not on our cars. Are there any of you out there that still have car payments and how are you making progress? We’re going to sell our timeshare in Williamsburg, VA too. Thanks for your suggestions!
