Yeah Ok, hes smart enough and thrifty enought to purchase used things on craigslist but doesn't know how to or can't learn how change his own oil. there is no way you can convince me that by doing your own labor, a oil change or even a tune up costs any where near $150 or $1000 respectively. You can buy the best oil made, Mobil 1, in a 5qt jug at walmart for 25 dollars and the filters are probably like at max 10 bucks, so thats 35 dollars and 30 minutes time every 2 or 3 months. On the issue of tune up spark plugs don't cost that much, furthermore it shouldn't need but one every few years or so, so that cost is blown out of proportion too. Props to the kid for being street smart but booo for being too lazy to change his own oil.
