NHC iDsi – take it or leave it?

Hi,
I own(?) a 2007 May NHC bought through my current employer. I am taking up a new job and hence have to buy back the car from my current employer. Rough estimate is about 5.5 lac that I have to pay back to get the car in my name. I am inclined to do that. My question is –

Is this a decent option? Should I a buy a new car with 5.5 ( I will get a hatch, though I preffer a sedan)?

Thanks,

P.s. The on-road-price was 8 lac when I bought it
