For Sale: 1998 Pontiac MECHAM Trans Am, #004, built LS7/427 570rwhp
This car is production number 004 Mecham T/A built in 1998, the fourth Mecham Trans Am ever made. The car originated from Bob Howard Pontiac of Oklahoma City. I have the original window sticker as well as the Mecham dealer display sheet and a written letter of authenticity from Dennis Mecham. The instrument cluster was sent to Mecham Design and autographed by Dennis Mecham, an extra touch done by original owner. Have quite a large amount of documentation of mods, builds, parts. The car now shows almost 46k on the odometer and approx. 3500 miles on this engine, and has been garaged since it was new. The interior still looks like new with little wear on the seats; in fact, passenger seat was rarely used, rear seats, probably never. Ashtray probably never had a cigarette in it. The exterior is in excellent shape as well. Paint is excellent for its age, even for a much younger car; there are a few small chips and scratches, the worst are on rear edges of headlamp covers, the easiest part of car to paint. Body very fine, no dings larger than a thumbprint, possibly PDR. There’s a tear in the driver’s window tint. Photos attached of all flawed areas. From the genuine GM LS7 block to the carbon fiber driveshaft, the LG Motorsports parts, this car’s build was aimed at ‘best of everything’. If you do not like attention from car-people, this is not for you. It turns heads and starts conversations wherever it goes.

Offhand, the only thing I can think of not functioning properly on the car is the driver’s side-view mirror motor; it moves the mirror up and down, but not side to side. Of course you can still adjust the mirror by hand.
NO A/C, removed by previous owner. Also, the 422CI stickers on the hood are from the previous build, as the car currently has a 427CI LS7.
