Welcome, it sounds ok on paper but things to check would be make sure there are receipts for all mods and a print out of dyno runs which prove what power it has as these cars need to be mapped if any mods have been carried out, the ej20 engine is a really good engine but still needs to be looked after e.g serviced every 5kmiles, black is quite a rare colour you don't see many about, also check rear arches, rear strut towers and sills for corrosion especially if it's a uk car as it will have seen a bit of salt from winter driving, good luck 👍
