The Santro XG was discontinued long ago, the closest you can get to it is the GLS. I have a suggestion. Why go in for a Santro when you can get an i10 for the price of the Beat? Sure, you have an i10 yourself, but another i10, say the all-new one with the new 1.0 K series engine,in the Era trim would be great for your dad!
I do not know if your dad will like the Beat's styling. I would say, he might favor the spark. Air for the LS, with its useful extras over the PS.
I don't think it is wise to have the K10 in the list. Apart from performance and FE, it doesn't have much on offer.
Wait a minute. Why not consider the all-new WagonrR LXi? It seems perfect to my mind. It has all the features he'll need, performance and FE of the Alto K10, Maruti peace of mind factor, and its a tall boy!
All the best.
EDIT: If you get discounts on the Spark, it will work out cheaper than the WagonR.
Thanks Arkin. Yea my mistake. It is Santro GL model which is close to 4L on-road in chennai.
i10 is going to come out with Kappa 1.0 & Kappa 1.2 VVT. Well Era trim alright, but there are already 2-3 i10s in our house. i10 seem to be way too common both on the roads and in our family.
Reason for Spark / BEAT: price point and features. I am inclided towards BEAT for its features and all aluminium 4 cyl 16 valve engine. Let me get the quotes today to see which model wins our heart hands down.
Good that your mind has turned over to go with a brand new car, I’d advice to go either with a Chevrolet Beat or Maruti Suzuki Wagon-R. Not sure why your family isn’t accepting it, but that’s a perfect and trustworthy model, otherwise look out for Beat, which has superior styling than any, and it’s a tall boy too. Don’t get pulled away with its sales volumes, which are more or less due to non-availability of diesel heart (Soon to come). Spark and Santro are somewhat dated models and lack the trend and excitement unlike their latest counterparts; unless new models, namely Chevy Beat and Hyundai i10 are absolutely out of reach, I do not recommend.
Out of your list i will go for Beat only. It was good styling and features , and the offers you seem to get is also good. I will strike out Xing and spark as they are comparatively dated IMO. Alto K10 is a good choice too but like your i10 the streets will be flooded with K10 in no time.
