17......jeez , I thought I was young at 25 buying my X5! But hey if you are making an informed choice go for it
Picking up on some of the themes....I can afford this car but I still don't like the bills at times. It does border on ruining the 'Xperience' (sorry couldn't help it) of this car. It just stings at times when all my previous cars have been tremendously reliable in comparison and not so over priced to deal with.....but hey its a rich man's car that comes with rich bills!

My friendly advice is consider the price ticket for possible major repair items that could possibly happen i.e. tranny, gaskets & seals, suspension etc not to mention preventative maintenance and if the bill scares you, then run while you still can!

Good luck
