Where the prices come from

The typical price is the middle of the asking and sold prices we recorded from sources whose terms allow this use (bonhams.com, classiccars.com, driveway.com, enthusiastauto.com), read October 27, 2026 to October 28, 2026, with 11 auction results sold between 2015 and 2023. A car fits a budget when its typical price is at or under it. 43 of the 69 generations have 3 or more such prices; a car with fewer shows “no permitted price yet” and is left out once you set a budget. Asking prices sit above what cars sell for, so treat a car near your line as a stretch.

Each list is ordered by the Guide Score’s parts weighted for that purpose (method v5-final.14), so a car can lead a list with a lower overall Guide Score; the score shown beside each car is its overall one. It is an editorial score, built only from permitted, sourced data. The cost to own is for a car bought at five years old, or its own age if older, kept five years. How it works.
