ERD feedback:

1. We need just one table for users, which will contain all user information. Hence, we will not need registration, login, reset_password, account_info.
2. Customer contact form does not need a customer reference. because, we assume that this is an anonymous user.
3. We don't need Customer table either, because orders can be associated with User tables directly.
4. Product table can be renamed to Vehicles.
5. Order can be renamed to Receipts.
6. We can move all the fields of Order_details to Receipt
