What to look for when buying an e46?

Hey guys,
On the market right now to buy a 330i. Just wondering if anyone can enlighten me on what specific details, or problem areas to look out for. Or anything which may lead to a serious and costly problem down the road.
I know the basics, cooling system, subframe (which doesn't seem to be an issue on newer e46s.) Anything other things to look out for?

1. Oil filter housing gasket - this is a common problem and is a pain in the neck to replace
2. Control arm bushings
3. DISA valve - this thing can break and sometimes you don't even know it. Pieces can get sucked into the block and destroy pistons if you're really unlucky.
4. VANOS seals - Up to you. I've replaced them in both my 328 and 330. Made a very noticeable difference in the 328 but I really didn't notice a big difference in the 330.
5. If you're looking at a model with a sunroof, the sunshade has plastics guides on either side which commonly fail. No big deal though, about a 20 min DIY.
6. Climate Control Blower Motor - I currently have this problem in both my e46s. At certain fan speeds they creek like crazy. Very difficult repair.

There are explanations of each of these problems on this sight if you want to get into greater detail. These are the main things i've encountered. These and replacing every part of the cooling system.

So much confusion surrounding this topic. People need to stop suggesting looking at common faults.

The question is what to look for... not what are the common problems.

The fact is no matter WHAT E46 you buy, you will have to address all the above and then some.

I'll do a thread soon on what to look for when purchasing an E46.

In short, body, interior, no signs of prior overheat or head repair.

Cooling, suspension, rubber, plastic, screws, caps, clamps, tabs, etc. etc. will have to be replaced regardless. (if you like nice things of course)

Hell, I received a whole shipment of screws, clamps, and clips today. (On top of the stockpile I already have) Replacing things that don't need to be replaced. That's what I do!

Thanks a lot guys. I'm definitely worried if a car has been overheated. Whats a good way to tell if headwork has been done. I'm definitely getting a ppi and I'm sure they can spot that out. Well I would hope so.

The head will be shiny and new compared to the rest of the engine. you'll see various tool marks, signs of parts that haven't been reinstalled correctly. for starters
