any car buffs, have a good knowledge of cars or in the industry, you advice is appreciated..

i'm looking at a BMW X3, 2005. It's in great condition and the price is good BUT it's got close to 100,000 miles on it. Cost is a factor so i can't go much higher and i like it for the safety features... Would this be a good purchase? Is it gonna hit 100,000 miles and require a lot of work or start having problems? thanks for your opinions...
