About Kurt
Kurt's passion has always been the rotary vehicles, despite the inability of the general public to embrace their concept or see their value.
Since 1983, Kurt has driven, bought, collected, disassembled and inventoried over 300 rotary vehicles, including R100s, RX-2s, RX-3s, RX-4s, REPU trucks/utes, RX-5 Cosmos, and dozens of RX-7s and RX-8s. These cars have become modern classics and are rightfully finding their way into the hands of owners that are looking to invest, restore and improve the performance of these unique vehicles (that's you!).
HKI, in association with Kurt Robertson Mazda, is proud to operate one of North Americas' largest collections of rotary vehicles and parts. You will not find a more extensive selection elsewhere. Feel free to directly contact Kurt with any old-school needs and technical questions.
