Recent purchase of used low mileage 03 buick

I recently bought a 2003 Buick LeSabre as a back up car. It has 118k on it, it drives well and needs barely any waork done to it at all. Just some new brake pads and maybe a valve cover gasket leak that is very small and i check the oil level regularly. It isnt losing hardly any oil at all and still has plenty inside the engine. I got it for 3500 in town. Did i make a wise choice? Also this car has the 3.8L V6 engine and it runs smooth with plenty of power (about 205hp) and good gas mileage.
