Mein Auto: 2001 325xi
New to bmw and need help!

So I am new to this forum and bmws all together and let me say, it's the best car I have ever had hands down(handling wise). I have a 2001 325xi inline 6 but it's my second day owning it and I think I may have bought a piece of crap. The reason... The radiator is leaking like crazy when hot and is overheating and hissing out the cap a bit so I put more coolant in and come to find out that there's oil in the coolant (I have the worst luck with cars) and has a milky substance on the cap from the mixture, so I check to oil dipstick to see if there's any coolant in the oil (because that's a sign of a failed head gasket or cracked head), but nothing. Oil was just changed and everything and no sight of coolant. So I check my trans fluid to see if that has any coolant in it. Nothing, from what I can see without draining it. Keep in mind that it's an automatic and has a very rough idle. The whole car just vibrates like crazy. Any help on what the might be? I would greatly appreciate it.
