Infiniti is worth it to buy and drives smooth

2003 INFINITI Q45 Premium Sdn

Good gas mileage! My motor is actually a V8 so it uses more gas than regular but still has a good gas mileage. Tires are affordable! Oil change is not too expensive either. I love my car even though it is a 2003. It drives smooth. Radio and other options of sound are loud enough!

- Gabriel O

It is dependable, fun to drive and gets fairly good gas mileage.
