Temperatures in Arizona this January are expected to rise.

We’re talking about those of the bidders at Bonhams Scottsdale Sale, which is now set to include the esteemed Oldenburg Family Automobile Collection.

It seems the Oldenburgs made a pretty good thing out of horse breeding and then set about collecting classic sports cars.

The impressive assemblage of over 30 autos is headlined by a number of fantastic Ferraris.

One of them is a 1967 Ferrari 365 GTC Prototype, a one-off created by the famed Italian marque for the president of another iconic Italian brand, Leopoldo Pirelli.

It was ordered new by the Milanese magnate using the existing 330 GTC body style but with the enlarged 365 motor, and fitted with handmade five-spoke magnesium wheels.

Considering the provenance, Bonhams’ estimate of up to $500,000 may be a bit on the low side.

Also on offer is a 1968 Ferrari 330 GTS Spyder, a 1962 Ferrari 250 GTE, a 1972 Ferrari 365 GTB/4 Daytona Coupe and a 1972 246 GT Dino Coupe.

Considering no two are the same color, you could buy them all and drive a different one every day, depending on how you feel.

Sort of a very expensive four-wheeled version of a mood ring…
