I'm only 16 and I've been racing offroad maybe 2 years but only every so often
I just got the Losi 8ight 2.0 and I love it
it drives great and it's hard as nails
haven't broken it yet, knock on wood.
It's a great handling car and if you want to get into racing I'd get it
But if you got the MBX6 then you'd have parts because your dad runs one
I'd say go with your gut and do what you feel is right
