Yikes, I think I'll stick to index funds and keep my own 1M which I can actually drive.
Cars are not good investments - 98% of the time they will underperform other assets. $50k invested in the S&P in 2011 would have at least doubled by today. The winners in the 1M game are those owners who have driven their cars 10-20k+ miles and had the value go up a little. You enjoyed the car while preserving the capital. Those who bought these and put 3-5k miles on them trying to maximize their return - you would have been better off elsewhere
