Just because that is what people ask, does not mean what they are worth. A mate of mine has 4 engines here in Oz that were given to him as no one else wants them. It was very common for people to give up on the M189 and replace it with an M130 as the M189 is complex, large, and expensive and a bastard to work on.
Be aware that this is an aluminium motor that uses steel bolts with typiclaly no protection in between them - so when they are not full of the proper coolant, they get bad galvanic corrosion. This siezes a lot of bolts, so they snap when you try to pull the motor apart. Typically, once you start pulling apart an M189 you don't stop until it is all apart as all these little things go wrong that require a full overhaul. Add in a big hole to let water in where the dizzy and injection pump should be, and I would say you have a siezed pile of scrap.
So unless you find someone restoring a gullwing that just has to have a particular part, I don't think it is worth much at all.
My 2c worth. Would love to be proved otherwise, as I will pull my running M189 out of my 300SE coupe right now and sell it for thousands!
