im including the system already installed...2 15" l7's hifonics 2008d ttb box etc.also keep in mind, if your getting a good deal, then he's getting a bad one. so why would he want to go down 8 years? your milage is lower, but try to figure out whats his objective
you'll be really good if his mileage is mostly interstate.in my book,lets say two identical cars have 100,000 miles on them.1 all city and the other all interstate,id take the one with all the interstate miles,because as crazy as it sounds,the interstate car will have less wear and tear.maybe the reason y my pontiac lasted for so long.
