Bought my first X5 3.0 (and first BMW) at an auction a few weeks ago. It's an '06 with 137k on the clock. Seems really tight and well taken care of. Drives great. But, I wanted to take it to a mechanic to see if there's any pressing issues. I trust him pretty well. He used to work on my Volvo XC90 (doesn't even compare to the X5). Here's the list of things he came up with:

Lower radiator hose and fan switch leaking - $226.00

Power Steering pressure hose from pump to rack leaking - $414.00

Power steering suction hose reservoir to pump leaking - $172.00

Power steering hose from reservoir to cooler leaking - $258.00

Vanos oil line leaking - $158.80

Left front axle outer boot split. Recommend replacing axle - $1164.00

Tension struts on front suspension - $633.65

So, my questions are

1) Which of these are actually pressing issues? I know PS hoses can tend to seep with age. I know some will say just do it all, but I'm not sure I'm ready to dump another 3k into this car.

2) I've done some work on my cars in the past, but never a German car. I'm a little intimidated by the BMW. Any repairs that I should just absolutely stay away from myself whether on this list or not. (I know it's hard to know not knowing my skill level)

3) Are his prices fair?

Any help appreciated. So far I've found this site to be awesome.

Thanks.
