They should command more than a standard 330, which I understand. But go on Autotrader and there's a firm out of St. Louis that has some ZHPs listed for OVER 22k and some in the mid to high teens with higher mileage. Are you kidding?
The extra 3-4k in maintenance...Isn't that like every BMW?
We have a bunch of people join the E38 forum over at BFc after having picked up a 740 with 150k miles for $1000. They end up spending 10k in parts in the next year just to get it running right and fixing all the old brittle stuff that breaks to get it back to business. Then the chain guides let go. It's a phenomenal car when running great and in good shape, but man you will still have a large annual maintenance bill because of the age.
I have no problem wrenching, but a car with 130k, 150k, 180k is still a car with that mileage even if it has been maintained. And age kills these BMW parts just as much as mileage. Anyone with a BMW plastic cooling system or timing chain guides can attest to that...
I'll just take my time and see if I can find a reasonable one. It's also difficult, because it seems if you ask too many questions about maintenance or condition of a car with 150k+ miles, you just get a short answer "whatever's in the listing" or stop hearing back. Rarely, it seems, do people have actual documentation of repairs. I have 2 binders of paperwork for my E38 over the last 240k miles.
