After overcoming numerous problems Dato' Haji Abdul Rahman made some initial success. He was encouraged by this and decided to really go all out to establish himself in the auto trading business.
He formed Syarikat Rahman Brothers Motor Sdn Bhd (SRBM) and decided to apply his own AP. After a long and tedious process he got one. With it he not only import from Singapore but went one step further. He ventured overseas by sourcing himself reconditioned cars from Japan and UK. Hence he secured himself into the auto trading business. And when in 1985 Proton cars came into the market and he was appointed dealerhip status and with it he was well into trading new cars too.
Around 1986 he transferred his business base from Johor Bahru to Kuala Lumpur to get into bigger things. He started to diversify into property, housing development, travel and tours and construction.
All along being a devout Muslim himself he never forgets his responsibility towards sharing and caring for others in need. This was evidence by the various charities he gave and the many mosques and surau he helped to build. He was awarded by the Sultan of Kedah a Datoship in 2000.
