I drove Ambassador for almost 5 yrs (old model) and I see today some improvement with PS /Isuzu engine etc..
This car is one of the best cars at High speeds also ( although it is limited to 130KM/hr).
It doesn't overturn so easily because of its inherent design ,however all other modern cars i know,don't have stability on " Braking" at high speeds and turnings./corners.
This car is the safest car I know. Even SUV's don't have the stability this car has, even otherwise some of other SUV's are costlier .
Believe me, this car is the best car I know for less overall cost and SAFETY at high speeds with Indian road conditions and long journeys ( Very comfortable with no fatigue).
"yes ",I do accept that it needs further refinement in mileage/ other features the modern cars have.(coil Rear suspension/ABS /Engine condition indicator etc/coolant level indicator-warnings/AT-Cruise control etc)
If further more refinement is done with features of modern cars , the market value of this car will improve drastically.
