Question 1

How is T-top different from Targa?

Accepted Answer

T-top has two removable panels separated by a center brace running front-to-back. Targa has a single removable panel over the front seats with a fixed rear roof. T-tops provide more open-air area (over both seats); Targas provide a single open area but a more rigid body structure.

Question 2

Are T-tops weatherproof?

Accepted Answer

When the seals are in good condition, yes. T-tops are designed to be water-tight when installed. The seals around the panels and the center brace are critical; degraded seals can cause water leaks. Older T-top vehicles often have leak issues as the seals age.

Question 3

Are T-tops heavy?

Accepted Answer

Typically yes. The glass panels add significant weight to the roof, raising the center of gravity slightly. Fiberglass panels are lighter but less impact-resistant. Modern equivalents would use carbon fiber panels for weight reduction; original T-top cars used steel and glass for cost reasons.

Question 4

Are T-top cars valuable?

Accepted Answer

For specific models. The 1977-1980 Pontiac Trans Am with T-top (the Smokey and the Bandit configuration) commands premium prices. Late 1970s and 1980s C3 Corvette with T-top is similar. T-top option pricing depends on the specific model and condition. Cars with the original T-top option in good condition typically hold value better than non-T-top equivalents.

Question 5

Why did T-tops disappear?

Accepted Answer

Multiple factors. Customer preferences shifted toward fully convertible designs as convertible engineering improved. T-tops were heavier than fixed roofs (added structural complications). Sealing issues on aged cars made the option problematic. Manufacturer focus on body styles other than T-tops also reduced availability. The format is essentially retired in current production.
