Johor ruler, Sultan Ibrahim Ibni Almarhum Sultan Iskandar, has achieved his dream when he took possession of the world’s most expensive Mack truck at a ceremony at King George Square in Brisbane’s central business district today.

The Super-Liner took a year to build at the manufacturer’s Wacol headquarters, south-west of Brisbane.

According to ABC News, the rig has some of the fanciest extras around, including a six-camera closed-circuit television system, two flat screen television sets, a stone-topped kitchen area, barbecue, double bed and seats with 72,000 stitches of gold thread.

It also boasts a solid-gold tiger hood ornament.

“This is my dream - am I smiling?” the sultan said of his ‘palace truck’.

The price tag is a well-kept secret, but smashes the previous record of A$481,000 for a customised rig.

The sultan said he was delighted with the end result.

“I have always appreciated Australia’s engineering skills and have collected a few Holden cars over the years.

“I am looking forward to showing its workmanship to the people of Johor as soon as the Super-Liner is shipped over,” he said.

The sultan ordered the heavy duty rig to tow his power boat around the country.

But his first drive will be a charity run when it arrives in Malaysia at the end of this month.
