#10: Cadillac Crest Dealer Sign (1940s) – $5,000
More crest than ad, this Cadillac sign delivers luxury in metal form. The gold-embossed crown and laurel detail scream elegance from every angle, even decades later. Likely hung inside upscale showrooms or behind polished glass, its condition leans immaculate.

It’s not garish or loud, but refined, just like the vehicles it promoted. Cadillac’s signs are usually subtle, but this one feels heraldic. Among car signage collectors, the brand carries royalty status, and clean dealer signs like this command high sums.
