Important Notice

All vehicle auctions are held exclusively online. Since we work with trusted vendors and partners across the country, vehicles are located at different facilities, so in-person inspections or visits before purchase are not available.

To help buyers make informed decisions, we provide detailed vehicle descriptions and CARFAX Report along with high-quality photos and videos for every listing. In addition, each vehicle listed on Biltmore Motors undergoes a thorough verification process to ensure authenticity and quality.

If you have any questions regarding a specific vehicle, our team will be happy to assist you with additional information whenever possible.

Free delivery is available within a limited distance after purchase. Additional mileage beyond the included range will be charged at a fixed rate per mile.
