I am driving uno diesal a/c since 3 years. it has an excellent pickup unlike diesal engines. it can take full load of 5 people and luggage with a/c on and still be peppy unlike other cars in it’s category. minimum maintaince. huge amount of inner space, both legroom and luggage. I think it is the best mid-size car for highway driving. average of 12 km on a/c and 15 without in city driving, it give much more on highway.the negatives are heavy steering and high engine noise. in my opinion till in our country the rates of diesal and petrol come close to each other one can go for a diesal car.
