Jenson Button was left gushing with excitement after his NASCAR-backed ride for the Le Mans 24 Hour Race came through its first major test this week.
Button is part of NASCAR's Garage 56 entry for the French classic this summer, along with Cup Series icon Jimmie Johnson and Mike Rockenfeller.
The trio really got to grips with their car in a 24-hour test on Monday and Tuesday at Sebring, hot on the heels of the official livery (paint scheme) reveal at Daytona over the weekend.
The feedback from all concerned was positive, with former F1 world champ Button particularly excited.

Writing in an Instagram post, he said: "I’ve been @sebringraceway doing our first 24hr test with the @nascarg56 stock car and it’s been a blast, working with great people with the same goal, to bring a competitive stock car to @24heuresdumans.
