High Mileage 2004 X3 2.5i Concerns

[X5HAPPY]

I am considering purchasing a 2004 X3 2.5iA that a local BMW Dealer has listed for under $13,000. It is literally in showroom condition and has the premium and cold weather packages, xenon headlights, and indicates it has Montana leather (question about that later.) The vehicle is an one owner car sold originally by the dealership. It has been maintained religiously by the dealer and the former owner was apparently completely devoted to keeping the car in perfect shape. Sounds great, doesn't it. Here's the rub: it has over 135,000 miles on it and from service records, it has not had (or required) any major component replacements. The owner had very long commutes and the vast majority of the miles were highway miles (not necessarily freeway.)

Drawing on the collective wisdom of this site, I would appreciate your thoughts and cautions on purchasing a 2004 2.5i with this kind of miles. I would consider purchasing an extended warranty to cover those large expenses that would ultimately be in the car's future.

I'd love to hear the experiences of any high mileage X3 owners out there.

P.S. The 2004 X3 Sales brochure indicated that Montana leather was not available on the 2.5i even with the premium package. How could I verify this vehicle has leather. (Manufacturing date on this X3 was February 2004.)

Thanks for your replies!
