i ran my xxx4 for 2 years, it was the best car i had since my bj4 we (i hated my yoke) i had a xx4 to but i didnt get on with that to well and was miles quicker with the xxx4. The best bit about the car was its amazing acceleration which i love the only bad point was its handling on the rough. that is why i am making the aero4 for a balanced cell layout with the aming acceleration of the xxx4. i think i also liked it because it felt like a 4wd car just like my bj4 does now the way you can chuck it into corners and hammer on the throttle on the way out....not that it will make me any quicker lol
