Nothing has gone wrong, but there are a few scratches in the paint.
The only bad thing I can say about this car is it doesn't have a lot of ground clearance. We have scraped the bottom over speed bumps when the car is loaded up with passengers.
The CVT transmission is smooth, and the power is impressive for a 4 banger, as is the fuel economy for a fairly big car.
I have an Altima 2.5SL. I've been getting 29 mpg in mixed driving (about 70% highway, 30% city) We've had some tanks where we got 36 mpg because we were driving on 55 mph roads with few towns. Winter driving has a definite impact on our mileage. We've seen as low as 24 mpg on some tanks due to cold and longer warm-ups. But in normal driving we see 28-30 mpg. What do you see for mileage? Have there been any unexpected repairs that you didn't mention?
