With only one known repaint and showing a believed-original 49,000 miles, it retains the integrity, look, and character of a true time-capsule Buick.<\/p>\n<p>Finished in the elegant Silver Mist finish, the car reportedly received its repaint in the 1990s and still presents beautifully. The original chrome and brightwork remain in striking condition, reinforcing the car\u2019s rust-free history and careful ownership.<\/p>\n<p>Inside, the Roadmaster showcases its mostly original silver cloth interior with optional leather trim, all in excellent condition. The dash pad is flawless, the steering wheel appears nearly new, and the interior chrome and stainless trim gleam with the kind of depth you only find on well-preserved originals. Even the factory AM radio functions properly and still produces that warm, vintage sound.<\/p>\n<p>Being proactive the owner had the entire cooling system completely restored with a re-cored radiator, new thermostat, and new water pump to handle Florida heat. The car now runs cool and steady, even on the hottest days with the A\/C on.<\/p>\n<p>When the original generator began to fail, it too was replaced along with the pigtail wiring loop, voltage regulator, and battery, leaving the charging system operating as it should.<\/p>\n<p>Overall, this 1958 Buick Roadmaster Riviera Sedan is a standout example \u2014 a beautifully preserved survivor with factory air conditioning, power accessories, documented mechanical investment, and an undeniable road presence. It starts easily, runs cool, cruises comfortably, and delivers the elegant ride quality Buick was famous for in the 1950s. A rare opportunity to acquire a premium, rust-free Roadmaster.<\/p>\n<p>&#8211;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>1958 BUICK ROADMASTER RIVIERA SEDAN \u2013 Exceptional Survivor, Factory A\/C, Only 48k Miles HIGHLIGHTS \u2022 Believed original 49,000 miles \u2022 Arizona-owned its entire life \u2014 rust-free chassis \u2022 365ci Fireball V8 with 4-barrel carburetor \u2022 Dynaflow transmission (freshly resealed, runs dry) \u2022 Power steering \u2022 Power brakes \u2022 Power windows \u2022 Factory A\/C (cold!) \u2022 [&hellip;]<\/p>\n","protected":false},"author":11191,"featured_media":1970369,"comment_status":"open","ping_status":"closed","template":"","meta":{"content-type":""},"product_cat":[18],"product_tag":[806,330,54],"class_list":["post-1970368","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-auctions","product_tag-buick","product_tag-roadmaster","product_tag-classic-car-auctions"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 -
