I bought used Uno diesel a week back and till now driven 700 kms. Its a 2000 model and still in a very good condition. Easily touches 100kmph. It gives 22 with AC on.
Build quality is very good and smoothly navigates potholes. Everything in the car is good and its aerodynamic design is excellent it gives great stability on the road even at high speeds.
Spare parts are costly. Apart from that it is a very good car for long drives with maximum 5 people.
