Worth buying w/145k and the need to replace noisy amplified muffler? Thank you.

What is your question?

Considering buying for my daughter a 2005 Passat GLX 4motion with 145k miles and good upkeep from dealer who purchased it at auction. Looks and rides great and title appears clear but I'm concerned about the higher mileage (should I be?) plus the noise-enhanced exhaust (pricey? complicated to remove/replace?).
