"We made a pact that if one of us won, he would give a monetary amount, but it was nowhere near $200,000," he said.
Jennifer McCann, a contestant who was paired with Jeremy Mayfield, said the contestants bonded over the weekend and during an earlier trip to Winston-Salem, N.C., when the fans picked their drivers.
McCann, who lives in Grand Prairie, Texas, said the other four contestants were elated for Grimm.
"It's really, unbelievably fantastic," she said. "We were in competition, but we got to know each other so well that if one won, we all won We wanted to win ourselves, but it didn't matter."
Grimm praised the "first-class" treatment he and his wife, Sharon, received from R.J. Reynolds. They stayed in a fine hotel and were chauffeured in a limousine wherever they went, he said.
McCann said the families clicked during the time away from the race track as well.
"We pretty much did everything together," she said.
Grimm, a longtime Dale Earnhardt fan, jumped for joy when Gordon won the race.
Grimm's daughters watched the race from back home, or at least they tried to.
"It was the best and the worst race I think I've ever had to watch," said Melissa Grimm, 26, who finally peeked at the screen on the last two turns. "I was totally overwhelmed."
Ray Grimm said he felt the highs and lows with his fellow contestants, who watched the race from the infield.
An early crash took three drivers out of the race: Dale Jarrett, Terry Labonte and Jimmy Spencer. That dashed the millionaire dreams of three of the contestants.
"I really did feel bad for them," Grimm said.
All they could do from then on was hope that one of the remaining two No Bull drivers, Gordon and Jeremy Mayfield, would win the race.
"They were the last two hopes," Grimm said.
The race also appears to have unified the Grimm family behind Gordon. Before the contest, Grimm's wife had rooted for Gordon while Ray Grimm was an Earnhardt man.
"I would say I've switched allegiances somewhat to Jeff Gordon," Grimm said. "But there will always be a spot in my heart for Dale Earnhardt."
