Sonet review after 5000 kms GTX IMT

I own this sonet since 8 months and have driven 15000 km so far. My driving experience of 15500 km so far. Combination of my previous car and this sonet. Coming to drive experience, its excellent drive on highways with good braking and stability. Suspension is on the harder side. During high speeds the cushioning effect is good, but if we go slow speed in city the pothole gives us more of an impact feeling. So city driving is good provided good roads are there .but if you have bad roads then you will get body pain. Coming to mileage, in city am getting 13 km/l and on highway getting 14.8 km/l with maintained speed of 100 to 110 km/h speed with normal fuel. If you use, speed petrol or v power from shell or xp95 petrol from Indian oil then, your millage on city will be 14.5 and highway 19+ and if you maintain 80 km to 90km/h speed then 20km/l Comfort level- Excellent on front row and second row. My family member's height is approximately 5.3 feet, so did not feel any uncomfort. But 5 members long ride is not advisable.(anything more than 4 hours journey) Service - so far done with 2 free service no complaint, 1- paid service. In paid service oil change and regular checks break and everything cleanup etc, charged 4700/- at 10000 km. So far no issues on service Safety - it has ABS & EBD. So twice I survived due to effective braking so ABS & EBD is good. Gear shift is smooth and since IMT has very good technology. Best for manual driver and city driving. No issues on gear shift. Cabin sound - Good insulation just like other cars. If you maintain 80-90 speed no sound in cabin at all. However if you go beyond this you will get some road and tyre sound. That is quite noticeable. Audio system - Bose - excellent. No words. After all it all depends on person's perception. I like it. Front seat cooling is more advantageous during summer. Luggage space is excellent. Cons - Night headlamp brightness is not effective. Even though it's LED. Suspension should be little on the softer side.
