Way to go on a great price for a Matrix! Im sure you will love the matrix, it is a very strong and capable buggy, so dont worry about that. I think they go cheap sometimes because Cen is not as well known as some of the other makes, so people shy away from them and their resale value reflects that. I purchased my matrix fre on ebay as well and got a killer deal on it ~300, even came with a ofna starter box and spektrum dx2 tx and rx. Oh and to fix that busted shock tower on your magnum, Dr. Honda is selling new designed much stronger shock towers for $25 a pair plus shipping, have a look at this thread "By request, ARO Funfactor Shock towers are back!!"
