Brother,
These Cars do not consume the petro/diesel. These cars "DRINK FUELS". Hahah
Hardly its consumption will be 6 ~ 7 Km/L and if engine is good, then max. can run upto 110~130 KM. But such turbo cars are usually for off road drives, such as Jungles, deserts, hill stations, etc. Not for the motorway.
By the way, what price you are being offered for it? Say if its 2 mil. rupee, then I'll suggest to search for more latest models.
Nevertheless, I fully agree with other post saying that buying a 1988 Accord / Galant /Corona or Sprinter would be the very excellent idea. I really love these cars. These are just like "quality bench marks".
FYR, maintains of these cars are v. expensive as well.
