Dear aisheikh bhai,
Following are my recommendations.
Considering your Budget , Fuel Economy, Resale, Offroading and family utility.
8-9lacs Toyota Hilux 1990-92 SSR NOT SSRX!
8-8.5lacs Toyota Land CrusierII, 2.4L 1988-1989 Reconditioned!(my friend sold one last year for 8lacs and it was reqistered in 2006!)
7-7.5lacs Suzuki Jimmy 1.3L Petrol with A/T Model 1998-199 reconditioned.
5-6lacs Toyota Surf 2.2L Diesel Two Door
4-5lacs BJ-40 Hardtop, 3.2L Diesel 1984 Model
4-5lacs Sujuki Vitara 1989-90Model 1.6L, 3 Door with CNG
There are many financial institutions that finance old vehicles. My friend has leased a 1996 Surf Recon.2006.
Some of these vehicles are hard to find but not impossible.
I hope other 4x4 members can comment on my humble research.
