I have always believed t-tops (or the "t-roof,’ or “t-bar roof”) to be the best configuration for open-air driving, but apparently auto manufacturers have stopped agreeing with me. Ten, fifteen years ago, it was easy to check the “t-top” box as an option for your new car, but in 2003, zero cars (by my count) offer them.
What happened? Have they been ruled unsafe, or too pricey, or what? When General Motors 86ed the Firebird and Camaro last year, with it went the only model(s) to still offer the venerable removable roof panels.
