Provide excellent customer service. Answer any questions buyers post as quickly as possible. Be professional and courteous. Positive communication builds your reputation with buyers and gets you return business. Also, package your product well and ship it out quickly. Allowing an item to become damaged or taking too long to ship can negatively affect your reputation among buyers. Wrap all items, especially fragile ones, in appropriate packaging. Commit to shipping items as soon as you receive payment.

Considering there is no effort needed by you, it’s a pretty good way to make money. That being said, your car will likely depreciate a bit faster by virtue of lending it out to other people. If you have a big car loan or are underwater on your loan, putting your car on a site like Getaround might not be a great idea.
