Tata Bolt is really a gem of car but in Bangalore I have never seen one. May be I have seen one but it may be a Vista as well. The exterior killed the sales of Bolt. Tata was never known for good mileage cars as well. No offence but IMO
even I don't like the outdated Vista exterior
Celerio on the other hand does not have a killer looks but it's not bad as well. Along with MASS, higher mileage and K10 engine is a better buy in my opinion as the looks does matter to me.
But TATA Bolt is a segment above Celerio and can't be compared. But even taking Grand i10/Swift/Liva/Brio I would have never prefered Bolt rather would have gone for Zest which is way better than Bolt and VFM
