I think the reason you see so many Punto / Linea v/s xyz threads is because a lot of people want reassurance before going in for a Fiat so they have a lot of questions based on Fiat's (in)famous past Indian innings.
Expecting Fiat to even remotely challange Maruti , Hyundai and Tata in India is day dreaming. We aren't going to see Fiat competing with the big 3 of India for many many years to come. I am guessing the current level of sales that Fiat is managing is the best they can do and probably they are happy doing these numbers.
The Linea sells about 1000 - 1100 units/month. Looking at Fiat's reputation in the market, I am guessing the best they can do is about 30 - 35% of what City is doing. That's roughly 1,400units (4000X35%). The Grande Punto should achieve about 40% of segment leader i20 which comes to about 1400 to 1500 units (3000X40%). I know i20 did 4K units last month but it was festival time so we can't take that figure as the average monthly sales.Let's also remember that Linea and Grande Punto are avaliable in only 99 dealerships across India. Surely Maruti, Hyundai and Tata have far better reach across our country then that.
Sure Spark is outselling the Palio (4000 units against 15 Palio's every month!) but on the flip side the i10 does 11,000 units every month against the Spark's 4,000. Why is that?
There are still a lot of issues about ASC's, spares etc when it comes to Fiat. Also, you may see a lot of activity online (again because people have a lot of questions and need re-assurance) about Fiat but out on the streets not too many people know that a car called Linea and Punto exist, my own Grande Punto was called a i20 sometime back. This disconnect comes because for most average car buyer's it's either Maruti or Hyundai or Tata. Fiat is pretty much no where on the mind of the average Indian buyer.
Perceptions though are changing. Looking at the performance of these cars by itself, there are about 1000 people willing to risk buying a Linea and 1500 people willing to risk buying a Punto every month. A year back, even Fiat maynot have expected that they would be selling 2500 cars every month.
Fiat in India reminds me of VW in North America. Like Fiat, VW in America have had major problems with dealers, poor service, spares avaliablity and reliablity. In fact, in comparision to VW's reliablity in USA, Fiat India's products are like Toyota here! Still, there are people who swear by VW out there. There are folks who will always buy a VW 'no matter what'. The reason is that VW's are great to look at, finished really well and sport the best driving dynamics in their segment for very decent amount of money.
There is something in Fiat's that make people love them. Call it soul or passion or that something typically Italian but it works and how!
I feel this time Fiat are on the right track but expecting their sales to compete with the Big 3 in just one year is expecting a very big miracle. The good thing is Fiat is going by their game plan on their own not bothering about who is doing what. I actually expected them to bring in the T-Jet when the Polo came in but they are all set to launch it in Jan. That's why I feel they are on the right course. For the sake of the Indian car buyer, I hope they finish this course, because in the past too, Fiat seemingly have been on the right course but somehow lost their way somewhere.
