a well thought out machine
 

I have been into RC for many years but have just ventured into cars. I bought a Team Associated machine. It came with a booklet detailing assembly procedure and each part with its' number, among other things, I have driven the car hard and broke a few pieces, all of which were readily available from Team Associated. I am very happy with the car as well as with the availability of repair parts. My question is if there is an upgrade from Team Associated as to durability, design and ease of repair with any other brand. I am only acquainted with this one, so I don't know if any other brand is an upgrade from this one. If so, how is it better than what I have?

You are talking about a Team Associated truggy?

ease of repair no. stronger parts sure but adding stronger parts will make break point in another location might be harder to fix if you add a stronger parts.
