Would you buy an Acura TSX 2004 with 84000 miles?

I just bought an acura tsx 2004 for 11,500 and it has 84000 miles. I just want to know if that is too much miles for the price, I put a 3000 down and got a credit union to finance it at a 9.9% apr since this is my first car I have doubt that i made the wrong choice. The car look great is just that a lot of my family member think that i pay too much for that car because of the miles. (they all drive toyota)
