There are currently two Alfa Romeo V6 engines for sale on Facebook Marketplace:

A 2.5 in Warwick which appears to be a pile of bits for ?300. Comes with wiring harnesses but the seller can't confirm if this comes with ECUs.

A 3.0 at ?950 in Bedford which appears complete but looks rather rusty.

Both would need a full rebuild but we would all do that any way; wouldn't we :-)
