Ah, first thread
. Was waiting for this.
I had the same dilemma. Always was a Xray fan but when it came down to these two cars I had to go with K1.
Mostly because the belt drive and schumachers experience in making good buggys. First car I have ever owned that I don't feel the need to modify anything on it.
Both cars are exilent. Seen xb4 also and it is a nice piece.
