I own a Fiat Linea since March 6, 2009. Specs, fully loaded ie Emotion with Options Pack. (This comes with Airbags, Alloys, Music System with Blue & Me, ABS etc. It has been and will be a great car if you have the right reason to buy a car. Let me say if you are an Urban / City driver then this is suitable for you also it is an excellent car on Highways. It is not for rural driving conditions as it is not built for it meaning designed for it.
Service/Maintenance quality has improved drastically, door step pickup and follow up call to check if you are satisfied by both the dealer and Fiat themselves.
Now as it is Fiat and it is catered to by TATA it is prone to step motherly treatment, we should expect it. And with the level of importance given to you by the dealer, you will be very much satisfied.
Except for ground clearance everything in the car is good. If you need highway stability at 170+ then obviously the car has to be closer to the ground hence low ground clearance. It has solid stability at high speeds and brakes are unbelievably good. Mileage turns to be around 18+ on highways and 15+ within the city. (till date have never rolled down the windows so AC is always on).
Places driven to by me: Cities of Chennai, Bangalore, Hyderabad, Coimbatore, Madurai. Ooty and Kodai reserved forest areas(obviously had to be too careful due to ground clearance).
I have done 15350 kms with 1st year service completed.
Pros:
Stability, Power, Torque, Comfort, Noise Proof(within cabin), Powerful AC, Theft guard, boot space, elegance and richness of owning it.
Cons:
Road clearance (it will clear all speed bumps), turning radius.
