I too have a tC. If the xB is anything like the tC, it should be pretty reliable. I bought mine in June of 2005 and haven’t had any issues (minus hitting a deer doing 65mph.) I will say this though, the Yokohamas they put on the tC’s are garbage. I hate them and can’t wait til I get some new rubbers for it. I’m assuming they use Yokos on the xB too. Just something to keep an eye out for.
