The 1958 Cadillac Eldorado Biarritz is a flagship American convertible from the Series 62 range, powered by a 365 cubic inch V-8. Sold new through Powers Cadillac in Pittsburgh, it passed from the estate of an original owner believed to be a Pittsburgh Glass Corporation executive to collector Dr. Frederick Prehn, who commissioned a meticulous two-year ground-up restoration to original factory specifications. The restored car earned top honours at Cadillac-LaSalle Club events, including Best of Show-Late at the 2010 Kansas City CLC Grand National.

Maintenance & restoration
- —RestorationMidwest restoration specialists
Full ground-up restoration carried out over approximately two years by Midwest-based specialists, returning the car as closely as possible to its original factory configuration per the build sheet. Work included reupholstering the interior in period-correct Jenkins Cape Buffalo leather, repainting in the original Rajah Silver Metallic finish, and custom remoulding damaged sections of the original steering wheel. A factory-correct air-conditioning system replaced the original dealer-fitted unit. The Cadillac-LaSalle Club Authenticity Manual was used as a reference throughout.
Documented by an extensive set of receipts and a photographic record covering multiple stages of reassembly; commissioned by Dr. Frederick Prehn.
