Go for a new car
Practically speaking only an XLI or City can be purchased with the budget of 17 Lacks
As for the question of new shapes... XLI will be about 2 lackhs plus the current price.
In a grown up world, an upgraded grill or a diffrent style of lights doesnt really matter so my advise would be to buy a new corolla at the earliest so that you dont have to pay added price for the new shape. A new car is always a new car.
City is not a bad option for youngsters but if your dad is also going to use it... go for a new XLI in black....
A few extra buttons dont matter. dont pay extra for a few gadgets that u will get fed up with in a week.
