I would suggest not replacing it, depending on the year I think it looks better without personally. Their are exceptions though, I have a 73, generally that year looks better without, but some years look like they have smaller pillars and different back windows(or maybe I'm just seeing things
). Either way, it might be a good time to look at your vehickle without the vynal and ask yourself, does it look better without, or with it on, because ultimately, only your decision matters(though one choice saves you a lot of cash).
