Hey! I wanted to get started in the RC Car Hobby.

Looking for some Used/New Off-Road Trucks/Cars under 15k. Both Nitro and Electric are okay.

Thanks 

Hi Vivek. If you are new to the cars then I would suggest you to start up with Electric Ones. Nitros are a bit Tricky especially at beginners level.  Posting some links.

Its not exactly within your budget, but afterall its HPI.

This is the one that fits in your budget but I guess its out of stock. But this vehicle is really good at this price point. You can all n ask Rc Bazaar guys when they are restocking this one.

Other than that there are some used cars/trucks are sale at RCI, go through sales section.
