and the losi buggy needs alum camber mount, .75 hex's, roll center blocks, kick plate, bulkhead, bleeder caps....... the base price AND the option parts are both higher.

I have had both and did all the options on both and can tell you that the Losi car is no cheaper (actually costs more). So pick the Losi if you want to drive one, no one will say you shouldn't, just don't make silly comments

About the only argument you can make against the 4.1 is the cost of the upkeep IF you don't want slop in the car. I personally feel the slop makes the car more forgiving and easier to drive. Any other arguments that people pose are applicable to every car on the market and are 99% of the time just driver preference.
