Its projection is built on a $73,688 purchase price and 13,500 annual miles, with the car assumed to be well-kept. Three years have taken $19,775 off a 2020 I-Pace's price — a 53% slide. What is left comes to a $16,900 total resale value, or $15,300 on trade. KBB now has the 2024 models down to just 48% of their original value after two years. This equates to $35,675 lost, with the resale value sitting at $37,600 and trade-in value at $35,000.
