As a few examples, a brand new Cessna Citation M2 (a light jet that seats seven) costs about $4.5 million at base price; the Learjet 75 (a popular mid-size jet that seats nine) costs about $13.5 million; and the ultra-luxurious Gulfstream G650 (a heavy jet that seats up to 10) has a base price of $64.5 million.
