I owned a Nissan NX2000. It was blue. It was the most reliable car ever. It does get very good gas mileage. It was so fun to drive and I never lost a race.
I had a Nissan NX2000 as well. It was Navy Blue and very fast. The only major problem it had was that the 5th gear would pop out of place. But other than that it was very fun to drive with the T-Top off.
