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).
