Pontiac offered 8 different color options for the Trans Am model in 1978. One of those colors was Chesterfield Brown which was different than the brown tones offered in 1977 and 1979. The Chesterfield brown had metallic flake and was more copper in color than brown. Here is a nice example that is well optioned with the two top performance options available in 1978 for the Trans Am. The car is listed here on Facebook Marketplace and is located in Austin, Texas. The asking price is a very reasonable $29,500. The listing has only been up for 3 days.

This Trans Am is loaded with power windows, air conditioning and the deluxe cloth interior. Everything looks very nice on this car. The dash does not appear to be cracked and the console lid appears to have been replaced with the wrong color but that can be easily dyed the correct tone of camel. There appears to be an aftermarket radio installed int eh dash but all the plastic looks to be in nice shape as does the door panels.

This was the last year for this design of the bird (1973-1978). In 1979, the bird was enlarged to cover more of the hood. This example is reported to have 89,000 miles. It is equipped with 15×8 aluminum snowflake wheels. If these are the wheels that came from the factory, it indicates that the car has the WS6 handling package. I own a Chesterfield brown Trans Am just like this but mine is a 4 speed. This car is in excellent shape and should easily sell at this price.
