Hey guys, new to the forum and looking at buying a 2015 450i on FB marketplace. Guy is only asking $800, apparently he let it sit last year and now it bogs down when he hits the throttl, who knows. I like messing with stuff, and have been looking at getting a cheap toy to mess with and play with. I'm no mechanic, but am handy and a tradesman, so my question is, are these overly difficult quads to work on? Would I certainly be throwing away $800, or is it worth picking up and trying to get to run right? Thanks!
