A 73 144 with B20B and M40, white on blue, but 622K km.

That's a metric speedo in there, but 73 models had MPH speedos when new. It's a 73 model cluster though, there's no additional warning lights to the upper right and left of the tacho blanking plate.

As much as I adore nice 73 model 140s like this, $10K isn't going to happen. Yes, it is one owner with a/c and full history, but the seller admits the car does need work (heater core / heater tap or hoses, which are One Year Special items).

I think this car has some connection to my 142, I think the original owner of this was also the owner of my 142, when I bought mine I heard about this car but never saw it, I was told the owners wife daily drove it for many years after he sold the 142.
