Price difference between ritz and beat is around 50-58k(base).Do you think it is a small amount.I dont think so.
Heard beat has better ride quality than ritz.Fro personal experience from chevy beat petrol,the ride quality is very good for what we pay.The reason I opted ritz was it give you a proper mjd.I city I think beat would be more driveable as it has negligible turbolag.If it is highway,oh boy ritz would be ahead of beat. Beat is good city car,i10 buyers would get attracted to beat.Ritz is bigger car,beat would easy to park in a city i think(I think kappa starts at around 4.2lakhs,beatD at 4.3lakhs).
If I was in such dilemma,I would save up to get a punto ative or all new swift ldi.
I dont know about the outside visibiity of the ritz for short drivers,but beat has visibilty issues especilly for the short ones.
