Hi Larry, I used to have a 12X and although I liked the car from the handling side of things, I did n't get on with the reliability of the chassis, especially around the lower area of the motor pod. It did n't seem to take alot to break a t-bar, but it also broke the carbon lower pod plate and the extra fibreglass bit that goes in between them. The Corally also seems to be the most expensive to replace these parts and I got fed up with it in the end. Unfortunately for me, I do hit the odd barrior every so often so do you know if Corally are going to do something about 'beefing up' this area of the 12x? Quite a few of the guys at our club run them so would be interested if you knew anything about this! All the best mate, Chris.
