What is the resale value of the Tour M as compared to the Ertiga?

While most of us consider resale value while buying a vehicle, especially in the Indian market where it can make a substantial difference to one's total cost of ownership. As a commercial version of the Ertiga, the Maruti Tour M poses a few intriguing questions regarding its resale value, relative to its consumer oriented counterpart. Higher mileage, commercial use means more wear and tear, perhaps less to start with, could all come in to play with impact on its future value. Furthermore, the resale prospects could be undermined by the fact that the used market for commercial vehicles is comparatively limited compared with the wider market for family MPVs. A discussion on this topic often includes the long term financial implications of selecting the commercial variant over the normal one, and if the initial saving is lost in the subsequent resale value.
