Question regarding the purchase/restoration of a US-Classics

Hi guys, first of all, I found the page here about google. you seem to know each other. therefore I wanted to ask you a few questions. my brother and I would like to buy us a us-muscle car for restoration. we have a garage for restoration as well as tools. my uncle is kfz-master who would do the welding and motor work for us and also knows a paintr who would make us cheap. we can get up to ~3000 euro for the purchase we don’t know at all where you get such a car from. everywhere at mobile.de etc. the carts are already restored. at ebay I find the cars very expensive. we are also ready to invest a lot of time in the car i.e., completely dismantle and grind off the whole car body. so we would like to have a real muscle car like mustang, gto, charger, chevelle or something like that. a cabrio like an impala or a fat street cruiser like e.g. a beautiful lincoln mark or so would be OK. we know that we will certainly not get a mustang with the budget but you know now about what we imagined. so the 3000 are only expected for purchase, we could of course apply something for materials and spare parts monthly, which like I heard are very expensive and difficult to get. therefore it would be nice if most parts were available. maybe there are similar but cheaper ones. tos?! and especially where is there? I know that there are many such cars in holland and we live just 100m from the border away so if you know the address that would be great. so my uncle knows something about muscle cars and would support us in buying and restoring, so that we don’t buy the cat in the bag. he just doesn’t know where to buy the dinger cheaply. so if it’s with the kale da garnix to make it says better gle i :/ I cordially ask for constructive proposals and under circumstances also direct vehicle offers. greetings mo
