I thinking about upgrading my main car (t4 19) is it better to go for the x4 or stick to the t4 latest model?
My concern about the x4 is that it will be more fraguel then the t4, we have some crashes

No real track, hardwood indoor in the winter seasson and parking lot in the summer.

But competition is hige and everyone is running new vbc d10 but iam happy with xray so no plan on changing brand
