Extreme reliability, great gas mileage, and an epic sound system.
The Infiniti drives smoothly with fantastic mileage. It offers great confidence in reliability and hasn't had many issues requiring maintenance. The few things it has needed over the years haven't been a strain on the budget. And it has an epic sound system.

It's a very compatible car, fills up well with only $30.
I really love my car because its very comfortable and well designed. It's an absolute beauty, it's the perfect gray. I do not like that sometimes the engine just somedays wants to work and other days it does not.

It still works well over fifteen years later
Nothing, I just wish I had Bluetooth connectivity. It runs well. My ac and heater still work. No major issues. Power lock and windows and android still work. My radio and speakers still work. Oh my CD player does not work. So that may be a problem. But overall I really like my car, and the mileage it gets.

Old car but is decent car
Runs very well just is getting old and doesn't have the new technology like the other cars on the roads today. But if you need a car that will run good and be smooth then this car works very well. Gas is very cheap and you can go a week with a tank depend on how much you drive daily
