Good condition Classic would fetch not less than 1.70L.
Gypsy starts from around 1.50L.
Very well maintained Jeeps could be yours for ~ 2.5L.
In case you want to get junk & then try to turn it into Gold, it will be a hectic affair & offroad performance would not be great. Failures & frequent garage visits are common in such egs.
If you want custom made Jeep, maybe Willys or other army disposal jeeps, try out in Mandi Dabwali/ Moga in Punjab, they are mecca for converters.
