I bought Mahindra Logan 1.4 GLX in 2008, I am satisfied with car performance, space, reliability and mileage.
What I did not liked in Logan is:
Service: I did all 4 four services in Sireesh Motors, ever time, service was equally bad. Once they left scratch in body. Once they left 2 sparks plug open and deliver the car. This time again scratch and no wash.
Hard drive: Gears are hard, not very easy to drive by females.
Overall its a good car if you find a good service center to service it.
