At one time the 500 had some camshaft issues, so I have read. You might want to some research there. If properly maintained 2-3k miles would not be an issue for me. All depends on condition and maintenence of the machine. There are blue book values for these machines and...does the dealer offer any type of warranty?? I own a 2015 450i with 2500 plus miles with no issues. I do keep up on all maintenence!! Keep us posted....
