If you have enough cash, is it actually cheaper to buy and run new cars and replace them before they need major repairs and parts and still have a strong resale value, instead of buying used cars that run less efficiently, need more attention, give more trouble, and depreciate in value? MSD
In a word? No. Across the full range of all motoring costs from purchase to resale, new cars are (almost always) more expensive. Often much more - not just by a percentage, but by a multiple!
