your car honestly has ANOTHER 175k left in it. it's a honda! no worries. as for value, it's probably only worth about $2500 - $3500. i wouldn't advise putting that much into it. i say keep it running, drive it until you get sick of it, than get something nice and new. the nice thing is that as long as the paint is ok, it's not going to depreciate anymore. if you want to keep it for a few more years, do the mechanical stuff, but don't spend the money on paint because you'll never see the return on that investment.
