I don't know much about the used car situation in the USA or anything about the new car tax. For me , if I loose less than 15% of the new car money (Tax included), I would buy a fancy car before Emira arrives. For example, a new M3 costs $138000 (Tax included, 10% of purchase tax )in China, if I could get no less than $118000 when I sell it after 2 years, I will buy it.
