To be a real gas saver, you should buy a new SUV or heavy-duty pick-up every three years, while the engines are still in their prime. If you can't sell the old one then just dump it. They're more environmentally friendly, dust-to-dust than greenie cars, don't 'ya know? In fact, you should buy them more often to help offset the growing environmental impact of those dang nu-metal hybrids. The perfect gun can be rearranged in all possible combinations. Jesus is on Facebook and He wants to be your friend.
