Well as the topic subject says it all...
I want some help to decide and aswell buy a decent RC drift car...

shoot your advice and suggestions please

guys also lemme know where can i get them in india

Drift Cars require some experience AND A WELL TARED ASPHALTED ROAD OR PARKING LOT.
Do you want Nitro or electric?
This is what I have http://traxxas.com/products/models/nitro/4807nitro4tec33 minus the telemetery part.
This is one fast car. requires a certain skill level and experience with Nitro none of which I had before I purchased this  but I have learnt a lot from the manual and forums online. Spent about 4 times the cost on parts more on that later.

For the best advice on what to buy I suggest you check out traxxas India website AND Hpi India (www.rcracinghobbies.com) Rahul will more than advice you. Joy rising hobby @ Murali very helpful passionate and cost effective solutions.
If you rather talk to them on the phone I suggest you pick up the phone and dial them directly and clear your queries.
Get a car that has maximum spares domestically available you will need access to spares (delays make you loose interest).
Heard Rotor.co.in has some options too.

Good luck hope this helps
