The best thing about IMT is the ease of shifting gears without a clutch. It takes about few kms of driving to learn about without an actual clutch. The engine is very very smooth and extremely silent.
Have driven around 20000 kms both in the city and highway. It is fun and easy to drive. The cabin comfort is excellent and the trimmings are very good. My wife also drives the car in the city and the highway, she is very happy. We easily cruise 120 kms per hour. The journey fatigue is zero. We just finished Belgaum to Bangalore in 6.5 hours covering 520 kms.
One small issue it doesn't have that extra punch to over take or climb very steep hills with 5 passengers on board.
