Ronco Motors commenced operations as a family business in approximately 1960 from its existing premises in Pinnaroo S.A.

Mr Bert Bailey (founder and grandfather of the existing dealer principal) a mechanic by trade, recognised the opportunity/potential in this Mallee region and established the garage/servicing operation to service the farm and other equipment of the farmers in the area. Bert based his business on customer service and good quality workmanship and was subsequently successful in applying for and gaining the New Holland franchise in 1962. He then began selling the New Holland range and used Agricultural equipment into the region.

In 1964 Bert's son, Rod Bailey, commenced in the service side of the operation and progressively worked in all aspects of the business, to gain the necessary level of experience to eventually take over the business.

In 1969 Ronco's successfully tendered for the Case IH franchise and the Pinaroo has been operating as a dual franchise dealership ever since.

Bert Bailey retired in 1973 and Rodney & Colleen Bailey took over the running of business. Since that time the operation has steadily grown into the well established and well regarded operation it is today.

Roydn Bailey (the current Dealer Principal) joined the business as a mechanic in 1986 and like his father Rod, he has worked in all areas of the business, taking over as Dealer Principal in July 2005 with his wife Louise. Fourth generation, Lachlan Bailey (son of Roydn Bailey) came on board in 2010 as an apprentice. In 2016, Lachlan successfully completed his apprenticeship and now works in the business as a qualified diesel mechanic.

 In 2014, Roydn and Louise expanded the business with the opening of the Loxton branch taking on the New Holland franchise for the Riverland region. Recognising the recreational industry of the Riverland Ronco Motors began a 'Power Sports' side of the business and took on the Can-Am franchise in 2017 and later the Seadoo franchise in 2018.

Ronco Motors expanded again in 2019 with the addition of the New Holland dealership located at Karoonda (previously known as WD Lewis & Co).
