When it came to the powertrain, the Seaders kept it simple, with a dressed-up original A-code 289 and Toploader four-speed manual transmission. With a factory rating of 225 horses, it's not horsepower that will win the Kentucky Derby, but it's plenty enough for a car designed for easy, trouble-free driving.

Even the brakes are stock-spec drums at all four corners, but they're hidden with disc-like covers that Tony Seader built himself. Crisscrossing the Rocky Mountains with four-wheel drums seems like more of a hair-raising driving experience than we'd prefer, but hey, some of us think ketchup is too spicy and some take showers while wearing a bike helmet out of the fear of slipping and falling.

The stock powertrain and brakes may not garner any Optima Challenge trophies, but that's just fine, because the Seaders' trophy case is filling up with plenty of awards from shows throughout Colorado and beyond.

"From the moment the car was finished, we wasted no time in getting in it and enjoying it—that's exactly why we built it," says Seader. "We have had loads of wonderful experiences in it, including many family trips to the Rocky Mountain Mustang Roundup, in Steamboat Springs, Colorado."

Indeed, with the success they've had there year after year, it would be hard to stay away. The two-tone fastback has nabbed three people's choice awards, a vendor award from Yokohama tires, and a number of excellence awards. Not surprisingly, the car's trophy haul has been just as plentiful at other shows.

"The show awards are great, but we honestly get the biggest thrill from the reaction the car generates from people on the street," says Seader. "We get thumbs-up all the time while driving down the street and strangers ask to take pictures of it. That's a lot of fun for us and very rewarding."

Such adulation is a far cry from the faded filly the Seaders started with about a decade ago, and we're sure a high degree of the attention comes from the great-looking fastback body style, which is an increasingly rare sight in either original and modified forms these days. Theirs takes the design into the 21st century without losing the characteristic form that makes it a true classic. Talk about a Rocky Mountain high.
