Its hard to choose a new buggy nowadays with all these good choices.
I've had just about every brand out there. They all have their pluses and minuses.
What kind of driver are you? Punched or smooth? It makes a difference as what buggy is right for you.
What kind of parts support do you have locally or do you buy everything online?
What kind of track or tracks would you be racing on most of the time?
What kind of cars are others near you driving? Do you wanna be the same where you can share set-ups and parts or do you wanna be different?
And finally what kind of budget are you working with?
The answers to these questions could probably lead you to find the right buggy for you. Otherwise your just going to hear what the best buggy for us is.
