I Can Comment With Certainty About The X5 ,i Have Been The Proud ,happy And Satisfied Owner Of An X5 Since 2002..the Vehicle Has Never Failed To Start Smoothly And With The Smooth Sound Of Driving Pleasures To Come That Day ...admittedly I Am Somewhat Over The Top When It Comes To Treating The Vehicle With Respect But At The Same Time Putting Her Through Her Paces At Ant Given Opportunity..after All Thats Why I Drive A Bmw, Tomake Driving As Much Fun As Possible.
A Far As Taking Care Of The X5 , I Can Only Be As Honest As I Am With My Son On This Subject ...take Care Of It And It Will Take Care Of You , As In Change The Oil Every 3000 Or 4000 Miles Tops ...lift The Hood On A Regular Basis And Survey The Engine Compartment ..all Clean As Possible And In Order If Not Get A Rag And Cleaner And Gently Put It In To Order ...as Far As Using The Machine Goes Drive Firmly And In Control But Gently ..let The Engine And Components Do Their Thing ,and Learn To Enjoy The Sound And Feel Of It .....every Green Light Does Not Have To Be The Start Of The Gran Prix..driving Can Be Relaxing And A Pleasure It Doesnt Have To Be A Scene From "mad Max"...hey We Are All Going To Wind Up In The Same Place Eventually Lets
Make The Trip As Rewarding As We Can .
As I Guess You Have Figured Out By Now I Love My X5 ..it Gets My Vote ,i Cant Speak For Anyone Else But My X5 Is Trouble Free And Reliable ...but Then Again I Treat It Right!
Good Luck On Your Decision Pop
