I am in the market for a Harley streetglide in a bad way. My buddy is selling his 2006 streetglide for 13K. It has the 88 engine, it has 24K miles...has aftermarket exhaust (dual fish tail), power commander, upraded speakers, medium ape hangers. Its in excelent condition and shinny black. should i get it or shop on for something newer like a 2011 or 2012 with the 103 engine??? $13K is about the max (perhaps a tad more). Any advice is appreaciated (my first harley BTW).
