I have a 2002 Harley Davidson F150 that I've been thinking about trading in for a 5.0. I really want to get back into a mustang but I'm concerned with what seems to be effecting so many 5.0s, the trans and cylinder #8. Probably going to look at a 2013 to try to get a better deal, definitely an M6, so what's the deal with them? Is this something that pretty prevalent and going to give me issues? I'm not looking to get something that's going to live at a dealership. Any insight is appreciated, thanks
