Santro or WagonR?

Well, the weekend was spent going to showrooms & trying to decide which car to buy...
I still feel Alto is the best car (for me, ofcourse).. But considering that space also a criterion, I decided to look at Santro & WagonR. Remote Locking & Music system are being offered free for Santro, whose price comes up to exactly 4 lakhs... As for WagonR, the price seems to be 4.2 lakhs. But the dealer offered to waive off the insurance fees & another 9k extra. So, the price of WagonR comes to around 3.98 lakhs, which is essentially the same as Santro. (But accessories-wise, you get a music system extra in Santro). If you look at the engine capacity, the inner capacity, boot space, the dimensions, etc, everything seems to be the same for both Santro & WagonR. There are a few differences though.. Santro is marketed as a 5-seater, whereas, WagonR is a 4 seater (but 5 ppl can sit comfortably). Also, the back seats of WagonR are fully reclinable, which is not possible in case of Santro. Also, if the back seats are fully folded, you get a lot of space in WagonR, as compared to Santro. Both has its positives & negatives. Mileage - Both of them claim the same mileage. So, it's totally a deadlock.. I can't decide which one to go for...

I have heard that the cost of spare parts & the cost of servicing are both high for Santro as compared to WagonR. The dealer dismissed these as just rumours & not just actual facts. But I have been told about this by many people.

Anyway, I have not yet made up my mind. The offers for both Santro & WagonR are valid only till the end of this month. So, I have to atleast book the vehicle (if not buy it) by the end of this month. If I were buying the vehicle entirely on my own, I would have bought it ASAP. But it's my dad who's buying it. And he's very religious & doesn't want to buy until after the end of first week of August, as he believes in not doing any good thing or starting a new work in the month of Aashada. So, I guess, I'll have to wait till the second week of Aug.
