Make sure local rules allow 4wd in rookie. Car is not THAT hard to work on. If you need to get to the spur that can be kind of tough but front and rear diffs are easy to get to. Buggy is quite durable and can take a beating but like anything if you try hard enough you will get something but they made the 1.0 which was one of the most durable 4wd buggies ever made stronger with the 2.0 so that is cool. Another option is 13.5 for motor. This 4wd buggy 13.5 class is starting to catch on and is a ton of fun.
