The cab sides wouldn't be visible in my personal line-up but certainly understand the desire for perfection on such a game.
It could be touched up fairly successfully I think. The glass looks to have it's damage limited to non-lit areas. I'd probably get scared and leave the play field alone until I could afford to have it professionally done. If it were mine I may be tempted to touch up the playfield and glass but I guess you can't go in half assed on a game of this caliber. I guess with a game this collectible it can get a little tricky. I guess based on my own games for the most part they are issues I could live with.
