The car looks the nuts

I didn't see it at tivvy, but saw it with lee at CML.. Looked rappid :O Apart from when it kept overheating on the like, last lap n stuff, but yeah, top car. the thing i would like to know, is the 'A-One' going to be the new xx-4?!?!... And also, what about the parts? Are they cheap or expensive? if it does become the new xx-4, God hopes the shassis wont be 60-70pounds :O ???
Thank you
