Milka Duno Third in Driver Point Standings after Mexico Race
Duno and Carpentier Finish 11th at Autodromo Hermanos Rodriguez

March 5, 2006...Drivers Milka Duno and Patrick Carpentier took the checkered
flag in 11th place after twice advancing into top ten territory during
Saturday's Rolex Sports Car Series race at the Autodromo Hermanos Rodriguez in Mexico City.

The results of the Mexico race will place Duno and Carpentier, who both
finished second at the season-opening Rolex 24 at Daytona, in third place in
the official Driver's Standings.

In a very rare caution-free race that certainly affected every team's
strategy and normal "race rhythm" - Duno and Carpentier both were able to
advance the #11 CITGO Pontiac Riley into the top ten - but ultimately were
not able to hold the position at the end.

The Mexico event was special for both Duno and Carpentier - and for many of the same reasons. Both CITGO drivers admire and respect the spirit, race
knowledge and support of the Mexican race fans. This was Duno's third race
in Mexico City and Carpentier's return from a several season absence from
his competitions during his exceptional career in ChampCar.

Milka Duno
"We are improving with each visit to Mexico - which makes me very happy. But I want so very much to do better for the fans here because they are so
supportive - it makes you want to do the best that you can. I was anxious
for the race to start because we had been improving throughout the weekend
and I was feeling really good for the start. But, right at the start two
prototypes got together with one of them spinning right in front of me -
slowing me down and placing me as far back as 15th - but I was able to
recover to my original starting position and even advance to 10th - which
unfortunately went away right at the end of my stint when my tires were
almost all the way gone causing me to spin right before I was pitting.
Patrick was excellent in his stint and if not for a radio problem we would
have had a top-ten. The team was great, the fans were great, we were almost great - and I look forward to a better finish for the fans next year."

Patrick Carpentier
"It was a difficult weekend. We did not have enough time to really set up
the car properly. Our engineers did their best but we never got closer in
test sessions than 1.5 seconds from the quickest car. Unfortunately, there
was a miscommunication between the crew and myself at the end of the race,
and I let a car by (#6 driven by Ian James) that I should have been able to
keep at bay to get a top ten finish. We will do better at the next race at
Homestead-Miami as we tested there late last year."
