Welcome to the forum and congrats on the purchase.
What kind of servicing has it received? Without any service records, I would assume little more than oil changes. I wouldn't be surprised if some of the fluids are more than 12 years old.

I would do an Inspection II and change all the fluids, spark plugs, and air filter.
Then there is the cooling system. When the cooling system has a failure, in less than a minute, the engine can catastrophically overheat.
BMW does not have a recommend service interval for the water pump, radiator, or hoses. Some water pumps have failed in less than 50k miles, other pumps are still going at 200K plus. Many pumps have failed in less than 80k. The same goes for the radiators; some failures under 100k, others are still going at 200k.
The standard rule of thumb is to replace the water pump at 60K, radiator and hoses at 100K. The hoses are probably are good for more miles, but get replaced by the "while you are there" rule.
As BMW replacement water pumps also only seem to be good for 60k, the Stewarts water pump is highly recommended - http://store.bimmerworld.com/stewart...6e46-p680.aspx
Coolant should be changed every 4 years and brake fluid every 2 years.

2. Engine Compartment
Read out diagnostic system.
Check engine cooling system/heater hose connections for leaks. Check coolant level and antifreeze protection level. Add coolant if required.
Check level of brake/clutch fluid in reservoir. Add fluid if required.

Check air conditioner for operation.
Check belt and pulleys
Check cooling fan and water pump for signs of looseness or leaking
Reset service indicator.
Check battery electrolyte level and add distilled water if required.

4. Final Inspection
Road test with check of brakes, suspension, steering, clutch/manual transmission or automatic transmission.
Inspection I items plus:
Half-shafts: Check for leaks at flexible boots.

2. Engine Compartment
Replace spark plugs (manual says every 60,000 miles)
Replace air cleaner element. (Note: reduce replacement interval in dusty operating conditions).
3. At Every Second Inspection II
Change oil in manual transmission while at normal operating temperature.
Change oil in rear axle while at normal operating temperature.
Check clutch disc for wear.
4. Brake Fluid Service (Replace brake fluid every 2 years (time interval begins from the vehicles production date)
5. Cooling System Service (Replace coolant every 4 years (time interval begins from the vehicles production date)

7. Fuel filter and power steering fluid are not mentioned but I recommend they be changed every second inspection II
