I am looking in scrap yards for a suitable heater matrix unit for my Luego Velocity using a Vauxhall redtop engine.

Does anybody know which cars have a suitable small heater unit? At this stage I think I will fit it in the engine bay and run the pipes etc. into the interior of the car but I haven't finalised that.

Polo, mini are the normal ones due to their size.

I've got an Austin Mini one, and it's a perfect fit...compact, simple hookup for hoses & ducting, 2 wire connect.
