An auto broker and dealer in Colorado

Specializing in high quality, hard to find cars and motorcycles


Glen Shelly Auto Brokers is a low-volume auto broker and dealer focused on the highest quality vehicles. We offer an informed and low-pressure sales environment resulting in a premium buying experience for you.


We buy and sell pre-owned vehicles, typically dealing in practical and efficient sedans and SUVs as well as high performance sports cars. We keep a small inventory of vehicles for sale that we have acquired through wholesale and retail sources and private sellers throughout the country. By keeping our inventory small, we can focus on thorough mechanical and cosmetic preparation of the vehicles we select.


Do you have a car to sell? Consignment sales are a core component of our business. We offer knowledgeable, detailed, and comprehensive listings that tell the complete story of your car, ensuring it will find a home with the right buyer. While under our stewardship your car will be kept in a safe and secure facility, only being shown to serious buyers under our watchful eye. We can correct any mechanical or cosmetic issues necessary to bring it up the best possible spec.


As brokers we specialize in high quality, hard to find cars and motorcycles. Are you looking for a specific model in a rare color? Are you looking for a specific model with a particular option package? We can find it for you. Glen Shelly has worked with numerous clients to find the exact car that the client was looking for.


Bart Rose and Alex McCulloch

Glen Shelly Auto Brokers is operated by Bart Rose and Alex McCulloch. We are two friends, airline pilots, mechanics, and auto enthusiasts who bring a high level of professionalism and attention to detail to the automobile business. We consider ourselves to be anything but stereotypical car salesmen.

We started the company after many long discussions between the two of us about how connecting the right person to the right car could build a better business in the pre-owned auto industry. We have over 20 years of experience restoring and repairing automobiles and are intimately familiar with our cars. We do the inspections, service, detailing, and corrective maintenance ourselves using only OEM parts and service manuals.

"You were seriously the most patient, informative, person I have ever encountered and always willing to put me before the sale…If the car industry took a page from you on how to treat their customers, it would forever change the car buying experience."
