You made it really tough decision.
First off you want it fast and good steering, I would say the Lst2.
You wanted it tough i would say lst2 savage or St1
and then you said gas or nirto.
I would def look into the baja 5b, cause you said price is not a issue.
But if you want the baddest all around your going to have tell us what you want.
Mt= overcome large obstacls, durable and not so good turning- Lst2 or savage
truggy- fast, durable, great handling, St1 or any other truggy
1/5 scale- Fun as hell, 45 min drive time, very expensive - Baja 5b
