After being the hottest item on an internet auction site, Australia's last Monaro is headed for cold storage. Queensland businessman Darryl Mattingley on Friday collected the keys for the final Holden Monaro made after successfully bidding almost $188,000 on eBay - more than three times the retail value. But rather than show off his own piece of motoring history, the beaming owner from Emerald, central Queensland, will ensure his investment appreciates by keeping it in a giant, chilled bag called a "car-coon". Asked if he was crazy for paying $187,600 for the $60,480 coupe then keeping it in storage, Mr Mattingley believed he would have the last laugh. "We'll wait and see three or four years down the track, see what the value is and we'll see who is crazy then," he said. Proceeds go to the Leukaemia Foundation. Despite the Monaro being open to anyone in the world on eBay.com.au, the final bidding came down to Mr Mattingley and a fellow Emerald resident. Mr Mattingley's winning bid of $187,600 last Sunday came just one minute before the 10-day online auction closed. However, Holden did not name the winning bidder until he arrived in Brisbane. Website eBay was also beaming after the last Monaro became one of its most successful auctions. It was viewed by more than 300,000 Australians and more than 160,000 people looked at the car specifications. The last Monaro was also the most watched item on eBay.com.au throughout the auction with more than 10,000 logging on. The auction was verified by trading assistant GoingGone which stepped in when hoax offers appeared within hours of the auction started following bids reaching $15 million by the end of the first day. If Mr Mattingley ever does change his mind and hits the road in his unique Monaro, it is guaranteed to turn heads. The colour is a distinct yellow-orange that is a throw-back to the classic original Monaro made famous in the late 1960s. Mr Mattingley described himself as a "life-long car enthusiast", who has bought and restored a number of cars including "a couple GT Falcons". "I think, being the last in the line, it will be a great investment," he said. "I also wanted to buy the car because the money is going to such a good cause." More than 47,000 Monaros have been sold since the Commodore-based coupe launched in 2001, becoming Australia's best selling sports car over the past four years.
