You can get a very good 120 series RX with 2.7L 3RZ FE for 3M.
A RX Diesel with 5 LE for 2.7M, and a TZ with 1KZ TE for 3.5M.
A V6 5VZ FE TX will be of 3.7M and TZ G will be of 4.2M.
The Prado in that AD looks pretty nice.
That Prado should cost 4.4M with 5VZ FE and 4.8M with 1GR FE with 5 speed Auto.
