The new XB8EC should be a nice stable car since the engine is moved more rearward and it has massive shocks to help on the bumps. The Xray is an awesome car in a lot of ways, great support from the manufacturer, awesome quality, and its just an awesome car to build. Of course there are so many options out there right now, but if I were to buy a new car it would be an XB8EC because it has the best of he reasons listed above for me.
