It's been a while since we washed our Q7, although it's always been in the garage but after a few trips to the snow, it did need a wash. We also want to check the condition after 3 years and almost 21k miles.The front brake pad's thickness is still good. We couldn't take picture of the rear, but they're still good also.

The front tire's treads are still good,... ... the center of the tires seemed to wear out more than the outside due to over inflated 38-42PSI.

The rear tires treads are a little better.

With the tires are a little over inflated, the gas mileage should be in the range of 16 MPG combination.

Besides a few spots on the front grill and bumper, the car is still shiny, click the image for more pictures
