The RM Sotheby’s Arizona 2018 sale was staged January 18-19 at the Arizona Biltmore Resort in Phoenix, resulting in $36,523,620 in total sales and an 88 percent sell-through rate. RM’s 19th annual Arizona Auction Week event featured a selection of 159 automobiles.

The top result at the 2018 RM Sotheby’s Arizona Auction Week sale went to the 1966 Shelby 427 Cobra ‘Semi-Competition’, CSX 3040. Offered four owners from new, CSX 3040 benefitted from a restoration by Cobra expert Mike McCluskey. The matching-numbers Cobra eventually soared past its pre-sale estimate of $2.0 – $2.4m to bring a final $2,947,500.

“While collectors across Arizona Car Week have been selective, there were clear signs throughout the century of cars we offered that the market is solid,” said Gord Duff, Global Head of Auctions, RM Sotheby’s following the sale. “Our top lots such as the 1966 Shelby 427 Cobra S/C and the 1948 Tucker 48 show that demand remains strong for rare, well-documented, expertly restored automobiles that are priced attractively. The two major single-owner collections we were privileged to offer – reflecting starkly different parts of the spectrum from pre-War classics to modern sports cars – showed the power of no-reserve lots to attract multiple bidders and send prices over the estimate.”

The ‘A Century of Sports Cars’ collection featuring eleven Italian sports and GT cars was offered entirely without reserve. Results for the collection were highlighted by the restored 1964 Ferrari 250 GT/L Berlinetta Lusso at $1,682,500, a 1960 Ferrari 250 GT Cabriolet Series II offered from two owners over the last 30 years at a final $1,407,500 and a 1955 Alfa Romeo 1900C SS Speciale by Boano at $1,270,000.

A selection of pre and post-war American Classics offered entirely without reserve from a private collection on Thursday evening elicited numerous above-estimate results, led by the 1948 Tucker 48, chassis 1029, the personal car of Preston Tucker himself until 1955. Star of the 1948 promotional film Tucker: The Man and the Car and presented with documentation, the Tucker achieved a final $1,792,500 (Est. $1.25 – $1.5m). Also fetching a strong price was the 1935 Auburn Eight Supercharged Speedster, retaining its original chassis, engine, and body, which surpassed expectations at $769,500 (Est. $500 – $650k).

Additional moments from the two-day RM Sotheby’s Arizona 2018 sale included a 4,540 km 1993 Bugatti EB110 GT offered out of single-ownership from new sold for $967,500, smashing the previous auction record for a GT example, a 1907 Ford Model K Roadster emerging from single-family ownership since 1957 brought a record model price at $252,000, and a 1977 International Scout II Traveler Custom drew a final $128,800.
