2004 BMW 330 CI ZHP with 150000 miles for 8k. Worth it?

Hey guys, I'm looking at grabbing a BMW 330 ZHP that has about 150000
miles on it. The vehicle history report looks great, as does the maintanence.
Should I be considering this car, or is it going to be a nightmare for me? And
the price of $8,000, is this worth it? I've seen some ZHP's go for as much as
$ 20,000 (but that's at like 50,000 miles).

I'm aware that cars with this sort of mileage are going to have some parts fail
within the first year of owning them, but it also seems to me that BMW's can
live to 300k if taken care of properly. If you think my yearly maintanence cost
would stay around 2-3k per year, it's worth it to me, as I had a ZHP when I
was younger and I really miss it.
