Absolutely right.It did happened with me to,they tried to push me with VXi(non ABS) model,when i asked for ABS,Reasons:
1.do u drive daily?no then,why do need it?
2.ABS tend to brake much faster then non abs,which may damage your vehicle.
3.If an ABS part fails,you might have to shell out 35k for repairs.
4.Your car delivery can require 2-3 months.
I do think that a guy who is spending 8 lakhs for his car,wont mind spending 10k more ..
