Welcome back to the forum, you have been away for a while, 5 years! Nice to see your two cars side by side, the limo style of the CX next to the more angular BX. Sounds like you have a bit to do regarding the BX but at least you seem to know what needs attention. Keep checking in with any progress and pics when you get started as you suggest.
All general chat and questions relating to the BX 16valve.
Prefer it to the Lamborghini, like Signor Gandini!
