It's not everyday you walk into a garage and clock a 1937 Lincoln-Zephyr. The famed Coupe-Sedan, with its sweeping lines, sold an impressive 29,997 units when it hit American roads, but today its more relic than grocery getter. At Austin Speed Shop, the Zephyr is symbolic of one sweet custom program. 

Should you want a one-of-a-kind car built, Austin is the place to go. The Speed Shop specializes in restoring classics. You'll see Chevy Camaros, Ford Thunderbirds, and other icons of American muscle. More impressive are the bombs, the '30s,'40s and '50s whips (like the Lincoln-Zephyr) that have become lowrider icons. Lovingly restored, these become trophy rides worthy of respect and plenty of double-takes.

Don't take our word though. Click through the images above to tour America's coolest custom shop.

Austin Speed Shop is located at 1414 S. Lamar, Austin.
