Is it reasonable for a $5000 maintenance bill

[milinatw]

Hi,

4 years/50000 miles warranty coverage was expired last year for my 2002 X5. I forgot to purchase the extended warranty. It had run 60000 miles. This week I sent my X5 to BMW dealer for Inspection II service. The estimation cost is $5000. Is it reasonable for a "BMW" car? The maintenance fee is such high after the warranty expired. Following is the detail:

1. Inspection II and oil change ($1000)
2. Drive Belts
3. Rear Brakes
4. Front Drive Shafts
5. Thrust Bushings
6. P/S Hose Pump Torack

The firs one is $1000. Let's fine. But item 2 to 6 costs $4000. Do you have the same problem? Or I have bad luck to have a defect X5.

Will you fix by BWM dealer or other independent shop after warrant expired?

Should I trade-in to get a new X5, or pay $5000 to fix the car?

Next time should I sell my car before warrant exipred, if the maintenance fee is so high?

Thanks,
Michael
