help me find a good X5M please

[bmwx5mnow]

Hello friends,
I've been a BMW guy for a while. Had several M3s(several E46s and a 2008 and a 2012), M Roadster(1998-2000-2001) and M Copue(2000) previously. I bought my wife a X5 4.8 before as well as several 3 series cars. I ended uo modifiying just about all of them.

It's time for a bigger car for me. So, here I am shopping for a X5M.
I can afford to pay up to $30K. There are several 2010-2012 X5Ms out there. Also a few 2013s.
From what I can see 2013s have the upgraded lights. Any other noteworthy changes that might be worth getting 2013.
I would preffer a car with DP, flash, exhaust, wheels etc. and ofcourse as little miles as possible.

Also, is it a real bad idea to entertain the idea of buying 100K mile car?
I am planning a trip with the wife and the kids to europe with the X5M for few months. I know gas will be expensive but I rather pay for the gas and have the extra power. I can't do a sedan because we need the space.

I'd appreciate your opinion and direction in the matter.
