I don't have any personal experience of them, but the general view seems to be that they are surprisingly good, given that they are made in India. India does not (yet) have a good reputation for manufacturing cars, although of course that does not mean they don't make any good ones. It took the Japanese many years before they got it right, and many more before the world acknowledged it! I expect the same path will be followed by the rising stars in India, Korea, Indonesia etc.
I am sure that Ghurkas have many strengths, and it's nice to see that they already have ardent enthusiasts, but I would find it hard to believe that they are up to the (incredibly high) standards of a Geländewagen!
As a matter of interest, which do you rate more highly of your own vehicles?
