[Hurst525i]

I'm in desperate need of some professional/mechanical advice:

I've recently been diagnosed a leaking strut on the front right side of my 2005 525i. Parts and labor for this procedure are going to run just around 800-900 bucks with a 4wheel alignment. After doing further research and speaking with other mechanics - many of whom question why one strut needs replacement and not the other? I've a bit concerned with the future of this vehicle. If I remember correctly don't you replace struts together? Why would one strut go and not the other? If a vehicle is covered under a dealership CPO would a leaking strut or beginning of a leak be identified during the procedure?

I purchased this vehicle just over a year ago from Sewickley BMW just outside of Pittsburgh PA. Not only did they get top dollar for this vehicle but to make matters worse my CPO just expired at the end of January. Since the purchase of this vehicle I've replaced 3 Continental tires, 2 halo angle eye bulbs, and the Idle Control Valve Assy ($600).

Additional work I've been quoted is to replace all drive belts $185, with the addition of the engine belt tensioner an additional $706.00. My vehicle currently has about 76,000 miles on it. The body of the car is in amazing shape. But I'm at the point to where I'm considering trading it in to possibly upgrade to another vehicle after considering the fact a year later I've thrown about 3grand into the vehicle.

Anyone have any advice on work needed to be done? Would it be worth investing this type of money into a vehicle like this?

Any help or advice is GREATLY appreciated!
