Nowadays it is very fancy and trendy to invest in classic cars because banks are bastards and the system is a lie. Cars are big, expensive and bad for the environment: in fact there is no future, whatsoever, in cars!
So: why don't you invest some of your savings in 'bike-art'? These timeless Haro BMX bikes are like an expensive bouquet of roses. They will brighten up your house, and only become more beautiful while aging.
Just make sure to not give these diamonds to your son or daughter when they are turning eleven or so. Get them a proper 16" modern BMX and maybe, when they are in there 40's, they will catch some air on a vert-ramp on a 10000$ vintage NOS Haro bike.
Both classics retail at 1299, and are on pre-order right now.
