I dont know Supra's value in Pakistan coz you cant import fresh ones due to which the ones in Pak have high value. But as per my knowledge, there are two variations Supra SZ & RZ. SZ comes in auto & manual tranny without turbo. Whereas RZ comes manual with stock Twin Turbo's. SZ models are inexpensive. You can get an SZ at Jap auctions between $3000 to $7000 depending on conditions. An RZ from $6,000 & can go upto $25,000 depending on modifications.
Jap models are non expensive compared to US ones. A stock SZ in US can start from $15,000 upwards depending on condition.
