You are not going to get rich on these two bikes. But if you are willing to do the work, you should be able to get them in good working order with not much work.

Myself, I would do the bare minimum on the Apollo and sell it to fund the Raleigh redo. I think the Raleigh has more character.

I can't tell from the pics, but if the Apollo has alloy rims I would swap out the wheels between the bikes. If they are both steel rims, no need to make that change.

Do a search for oxalic acid treatment, there are all kinds of threads on that topic, and I highly recommend it.

The Apollo looks like it has a bigger frame, which one fits you better?
