Dean ended up developing feelings for Amber, which caused problems when it came to his relationship with Beth.
Things were made worse when Amber returned to town after just six months in LA, and Beth found out about her new job at the car auction.
Amber refused to co-operate with Beth and sell her cars, as she said she had developed a hatred for Dean. As a friend, Beth explained the cars would be for her, not Dean, as she had taken over Dean’s business.
Her last physical appearance was in Everything Must Go in season two, and from then on she was only mentioned in the episode Take Off Your Pants. She did not feature at all in season three.
Beth and Dean had agreed to trade roles, with the car salesman becoming a stay-at-home dad, so he would not see more of Amber.
