my car is a high-up car with my girlfriend and I love! the car is great for the price and I definitely recommend it to new drivers with a low budget!

My vehicle runs great! My girlfriend and I have been using a lot on recent trips all around the US. The gas mileage is outstanding and overall it is a very trustworthy car.
