Chad,Look at the bright side-- no one got hurt! Think about all the extra body work practice you'll get! Now you can reach the inner fender to fix the rust, etc., etc.
Seriously, I'm sorry it happened and understand how unhappy you are. Please take the warning and have your Grandpa teach you to drive it-- there are many different responses that you need to learn for stick shifts and he will enjoy the opportunity to spend the time teaching you-- Us old timers need to feel needed and this is a chance for him to feel important.
