mortgage vs car loan vs invest extra cash?
Since you've already maxed out your 401k and your IRA, if you wanted to invest more-- then it would either be in a brokerage account or a 529 (if you have kids/ intend on going back to school). As to investing versus paying off your loans -- the interest on them are small enough that it will depend on your preference.  If you need the cash flow for investment purposes (ie if you are going to buy an investment property) then I would pay off the car loan first -- otherwise I would invest the money.   Since you've already expressed that you wouldn't be too interested in paying the mortgage off early, I've left that off the table (I would prioritize car loan over mortgage for the cash flow reason)  If you do open a brokerage account -- make sure you are minimizing your taxes by putting the 'right' type of assets in a tax advantaged account.
