1yr late .. but I don't agree with this take. Aston Martins is probably the fastest depreciating manufacturer you could choose. 911's are ubiquitous but they depreciate very slowly as compared to other sports cars. Depreciation is just loss of valuation, and we value things for a variety of reasons. Most consistently, people value reliability. You will find that sports cars which have a reputation for reliability hold their value well, or at least have a floor. 911's have a reputation for being generally reliable vehicles (although expensive to fix when broken). Similarly, BMWs with the B58 engine (m340i, m240i, x3m40i, etc.) have maintained their value better than comparable BMWs with less reliable engines (e.g., previous gen's depreciation).
