I've bought ex demo BMWs in the past for large sums below the list price, but then I could have bought the same car new, also with a large, but not as large discount below list. I know Tesla are discounting now, but if we take the BMW example, a 60k list car can often be bought for 54k (10% off), and then within the first year it might drop to 48k, another 10% - it looks like a 20% fall but in reality its a 10% fall on what was paid. I always thought that wa the real reason why they always appeared to have a large first year depreciation as it was based lined on list and not tyoical purchase price., In other words, it's rarely as bad as the headline figures make out because of the initial discounting,
