Very nice Candyman
Tbh when I ran a B44 I found it to be pretty robust, barring the odd wishbone, wing mount & front shock shaft - In which they were done by some pretty substantial hits!! Reliability issues, didn't really find any just as long as I did the maintenance (likewise with any make of car)
As for the BX, I know one guy in particular in the north east who still runs his and to good effect
