In my humble opinion, the cowl lamps detract from the value. If I were buying, I'd wonder what else was done. No big deal to correct anyway. The trailer hitch would do nothing for me since the car is already heavy, towing anything would be a chore.
As for the oval tank knowledge, I own a 24 T coupe and have studied them almost nonstop for over a year. For additional reference, see this post by "Hap"
