That is too bad, looks nasty. Are you sure that all of them are burns? I had a similar bunch of what I thought were burns in the 1980 Cordoba that I bought. Resigned myself to gettting a new carpet. I did start to clean up the rest of the interior using a really good, but inexpensive cleaner. It was one of the type that needed to be diluted to be used, and had a bunch of dilution ratios; 10:1 for upholstery, 5:1 for carpet, etc. It cleaned up the upholstery pretty good, as well as the door panels. I decided to try it at the 5:1 on the carpet, figuring to get it as good as possible until I could get it replaced. Turns out the burns were actually dirt/grease spots, and came out entirely. I am not saying that you can get all of your burns out, as it looks like you have the same burns on your seat, but you can try to clean them anyway, and make them little less visible.
