Jonah Lomu's noisy wagon and the custom Kelly Tarlton's shark bus were the most popular viewed vehicles on Trade Me last year.
The shark bus sold for $31,500 after being viewed more than 195,000 times, while Lomu's SUV is still for sale despite being viewed more than 226,000 times.
His custom SUV was fitted with massive speakers in 2000, as part of a record attempt for the world's loudest car.
Trade Me says people came from around the country to see the "eardrum-bursting SUV".
Other popular cars for sale included Merv from Taranaki's 'Tesla Cybertruck' — a Toyota Vitz customised to look like the futuristic truck — and a Mitsubishi rejigged to look like the Delorean from Back to the Future.
Not all of the most-viewed vehicles were cars.
The original lifeboat from the sunken Rena Monrovia sold for $9800 after being viewed 94,000 times, while a futuristic UFO spaceship house was viewed 104,000 times.
