I dont know why people support the thai vigo so much so as if it is a much superior car.
I have owned a thai vigo and a local vigo champ
The fact is that in the current market you get a 2010 thai vigo which is 4 years old and 50,000km plus driven for 43-44.
after this you need to replace the tyres, battery, brake pads and do other maintenance which cost 2-3 lacs.
Even after doing this you are driving a 4 year old car which has older interior and older exterior and is not champ and you have no history of what repairs it has been through in thailand.
On the other hand the indus vigo is 0 meter, has a tv navigation, no major maintenance work for 3 years, and costs much less at 36 lacs for a new 2014 model car. It now even has 17 inch rims.
I currently own a vigo champ 2.5, and it gives me a milage of 9.3km to the ltr,
very satisfied and happy with it,
if by chance you feel it is underpowered, add a bolt on front mount intercooler which adds 15-18 hp, or get uni chip which adds 45hp.
Dont get a 4 year old car for a much higher price.
hope that answers your query in detail
