if i were u n want real returns take aside 10m and import 4 2005 Toyota harriers and 5 toyota ists and get a free fob unit either ist or new shape vitz. Since you will buy bulk the harriers will cost 1.7m each total landed cost and the ists each 600k. Buy coloured ones only beige, black, silver and park them at any reputable showroom on ngong road they should sell like hotcakes within 3-5months and the harriers combined should net 2m plus the ist combined750k. The free fob unit should get u at least 450k thats a cool 3.2m in at most 5 months from just a third of the cash. Cars are really selling you can select a reputable dealer like sbtjapan or delights and go there in person kobe city has numerous auctions that can fetch u good deals. U would need to pay me consultation fees if u need me to accompany u hahaha.
