So what's there to do - just as a matter of principle, I've spent the entire Saturday removing a new 1.9 D engine (originally from Xantia, driven 170 000 km) from a rotten BX that's on its way to the scrappers. Tomorrow I hope to get the broken engine off the Van and the new one in its place. If everything goes as planned, I'll get the Van back on the road by Monday, and THEN I'll decide whether to take it to MOT (due in 3 weeks) or not.
It's me - not the car - who decides when it's time to retire!
