Hyundai santro is the largest salling car in india in 2014 sntro production is stop by hundai company for purpos on many car which the hyundai is manufacture .Well, uniqueness is something which is the perception of the user and accessories are something for which everyone has their own taste.
To name a few - go for alloys, a nice muffler and projector headlamps to start off.You have quite a decent budget and a number of hatchbacks will be available on the same. You can easily find a well maintained Hyundai Santro ( 2010-2011) for 1.8 and if you don't mind buying a little older car then even a Hyundai Getz Prime and i10 fits in your budget ( 2008-2009 models) . Also, avoid going in for the WagonR, it lacks quality and has extreme amount of body roll which is highly unsafe. If you thinking maintenance will be an issue then let me tell you my friend Maruti Suzukis products aren't cheaper to maintain anymore.
