Don't believe the hype.
The Seattle area is great, but desirable locations eventually get expensive.
Washingtonians have gone too long with the poor & middle class bearing the tax burden (regressive sales tax) for those that make millions every year. A vocal minority (most of whom will never pay this tax) are creating fear over this issue.
As for mechanics & auto work, I would find a shop outside the city. Tacoma and Everett are not far.
Is she really going to live in the city, or commute like most do?
