9. Pontiac Trans Am 20th Anniversary
In 1989, Pontiac was celebrating the 20th anniversary of its favorite muscle car – the Trans Am. To do so, they presented a limited run of 1,500 cars to commemorate the occasion. But, they wanted the anniversary edition to be more than just another decal and paint job. So, Pontiac decided to install Buick’s, 3.8-liter turbo V6 from the GNX to create the fastest Trans Am of the decade.
The white commemorative edition could accelerate 0.1 seconds faster from 0 to 60 mph than the GNX at 4.6 seconds. The reason was simple. It had a better weight distribution and updated gearing from the Pontiac gearbox. The Trans Am 20th Anniversary model is hard to find, but quite desirable today.
