OK I have a 2002 Fully Loaded 4.4 X5. It is a CPO car and I've already been hit with a brake job($900)...radio replacement($500)...and a few little items which were covered under warranty. The car has about 63K miles on it..and I'm thinking about upgrading to a 2006+ or newer car. I found a nice 2006 X5 with 10K miles 4.8 with NAV (CPO)....I need some opinions here whether I should wait till early next year and look for a 4.8 or possibly look at the new 4.8's(which I'm not sure if I like the new body style). Please share your opinions...I'm looking to change out the 4.4 for something which will give me full warranty and full maintanence for the next 4 years....
