I work at the British consulate in Boston as the right-hand of a high-ranking consular official. The official, who I’ll call “Margaret”, is looking for a used, German-made car for her son, “Jasper”, who learned to drive on a stick shift and has said he’ll never drive an automatic car for as long as he lives. “Margaret” wants to reward “Jasper” for being such a well-behaved lad this year—the first year out of five he didn’t get kicked out of prep school. She’s asked me to help her find a VW Golf, but is worried about how much value it will lose. How much will a Volkswagen Golf depreciate?
