Welp, I got one.... it's the
black one. He didn't want to budge on the price, so I only got £250 off

Still, it's a cracking motor, very good condition, engine is spotless. Has some very minor stone chips on the bonnet but nothing interesting.
I must say, the engine is incredibly lazy. Nothing like my old 2.1TD unit. But very smooth and gentleman-like. Gotta chip it!
Picking it up on Saturday - fingers, thumbs and toes crossed for everything!
