"The plan this year was to win the first stage and keep winning stages because, if you win the first one, all you have to do is match everyone else's times from that point on and you will win the event by two seconds."
Heading into Friday's racing near Marton, Inkster and Winn were still in with a chance but an extra slippery corner early on cost them.
They never gave up, though, and their pace over the fast, flowing roads of the Wairarapa and Hawkes Bay was a sight to behold.
"I knew this morning that unless something happened to Tony and Naomi we weren't going to win," Inkster said. "But there was no way I was going to back off. I still wanted to win as many stages as I could, and I didn't want to get to the end and find that something had happened to Tony and Naomi but I hadn't done enough to bridge the gap."
With his fourth Targa New Zealand title secured, Quinn now returns to Australia to contest the Targa High Country event in Victoria next weekend, again with Tillett.
The big question now will be whether Quinn returns for the 2012 Targa New Zealand event to try to make it four consecutive wins.
"I'm not sure how much longer I can keep the pressure up," he said. "I will be there for as long as I need to be and I'm happy to continue to set the benchmark until someone better comes along."
Behind the duelling Quinn/Tillett and Inkster/Winn combinations, Glenn Smith and his co-driver Andy Lowe finished third, followed by Steve Millen and Jen Horsey.
In the Metal Man Classic section, the Kirk-Burnnand family were back on top after playing second fiddle last year. The young gun of the family, Mark, took the overall win in his BMW M3, ahead of his uncle Barry and Barry's son Steven.
