Should I buy this Toyota 4Runner?

Im a 17 year old guy looking for my first car. I really like the Toyota 4Runner. I found this used one that is a 2006 with 173,000 miles. Its a good car, well cared for and maintnenced, has all the features I want and is a good price. The only concern I have is the miles. My mom says that she thinks it has too high mileage and pribably wouldnt consider buying this car. But ive been trying to tell her that I will not be driving it that much and I wont rack up that many miles, and also 4Runners are very relible and will last well beyond 200k miles with proper care and maintenance. So my question is, do you think 173,000 miles is too much for a 2006 Toyota 4Runner to consider purchasing given the factors I listed above?
