First Car

Hi guys, first post here. I'm 18 and looking to buy my first car. I've been looking at mainly gs350s and rc350s in around the 100k to 200k mile range and wanted to know anything I should look out for before and after buying the car. I don't have much mechanical knowledge but I am going to school right now to be an auto tech so I plan to do some maintenance to the car myself. I'm really just trying to know everything I can about these cars before I go ahead and buy one. 😁
