Erick,
it looks as it was one of the best illustration of one of threads posted elsewhere at this site with title "rust bucket" or something like that.
As it is a conversion, forget to take it back to the concourse state
For that price you can source a much more decent car with original parts and without major rust problems.
I am not a specialist, but am currently having my car at restoration shop where they uncovers just three rust places (including all the three boot panels) that needed replacing.
Here you can see that most likely, the entire chassis needs revision and most likely replacement. I would call it car rebuilding and not restoration.
As a side remark, it appears to me that the current owner was not too concerned about originality. Besides the engine conversion, the tires are of Toyo, brand, which is nothing wrong, but far away from white stripe Michelins or alike
If you are a potential buyer, I would rather ask other Members if they are aware of some serious sources or run some reputable websites that offer Pagodas. In Canada, Dr Benz will certainly know, where to get a decent Pagoda.
Not that I cannot live without, but I would be curious to see other pics, so that I could try to understand what commanded such an exorbitant price.
