For over a decade, RM and Sotheby’s jointly hosted multiple auction events, setting the stage for the formalized partnership in 2015. The cross-promotional potential of this partnership is a benefit truly unique to the company.

With Sotheby’s being the first international auction house to enter Hong Kong (1973), France (2001), and Qatar (2009), RM Sotheby’s is poised to access the many opportunities in emerging markets in addition to Sotheby’s large database of collectors from traditional markets. The RM Sotheby’s partnership culminated in the record-setting 2015 auction in Monterey, California, where Sotheby’s tremendous inter-departmental presence from around the world contributed to nearly 25% of the gross sales that weekend—a categorical validation of the strategic partnership with Sotheby’s, one of the world’s oldest auction houses, which adds over 270 years of experience with the auction, appraisal, collection, financial management, and private sale of the world’s most desirable fine art and collectibles, a category in which collector cars are now firmly entrenched. RM Sotheby’s stands today as the only company in the world with the resources, expertise, and capabilities to handle any collector car or any automobile collection—regardless of size or complexity.

RM Sotheby’s is uniquely qualified and experienced in working with collecting families and their estate-planning attorneys and accountants to develop clear roadmaps for the management and dispersal of their collections.

Effective planning not only offers tremendous peace of mind, but it can also save enormous amounts of time, worry, and potential financial burden in times of great sadness. In most countries, estate tax returns are due less than a year after a collector’s passing, so it is crucial to have a plan in place to protect family members and ensure that all final wishes are carried out correctly, particularly with assets such as collector cars. As these have risen in value, only RM has developed the expertise to help manage a very substantial group of assets with significant tax implications for the estate and next generation beneficiaries.

We always strive to outperform both our clients’ and our own expectations, and this begins with strategic advice based on astute valuations, as well as our proprietary knowledge gained from the market insight that comes with the transactions we manage on a daily basis.

It is important to have proper appraisals on file for various purposes, including estate planning, collection management, probate, and insurance, to name just a few. RM Sotheby’s Appraisals team produces credible appraisals for any of these purposes, and they are tailored to the client and the job, ranging from informal valuation assessments to formal appraisal documentation following the criteria and standards as outlined in the Uniform Standards of Professional Appraisal Practice. RM Sotheby’s appraisals have been routinely employed to assess important cars and collections and have been recognized by the courts as well as tax and legal professionals in the process.
