A car that was so cheap when new that a trunklid was an option? The Henry J was such a car, and Evestay has found an example that still survives on the streets of Denver.
Buyers who didn't want to splurge on the frivolous trunklid option had to fold down the back seat in order to get access to the trunk. Try explaining that to the Yaris buyer who whines because he has to pay extra for cruise control!
