My dad went to dealer with his dad when he was 16 back in the 60s. He test drove a manual, and after the test drive, his father asked him if he had ever driven stick before. His response: no, why?
Go to a variety of dealerships and see how long they'll put up with you not knowing how to drive a manual. When you stall the first vehicle ten times trying to get out of the parking spot, blame the clutch and ask to drive a different model in manual. See how many different cars they'll let you test drive. For the entertainment of the forum, please video and post here
