“Actually, it would be in your wife’s best interest to establish her own credit”
Absolutely.
And she does.
Two complicated.
We bought a previous car in my name with my wife as co-signer because--- well, that's the way it was always done.
It didn't take much thought to see the value of her having the primary role because it accrues many benefits, among which is avoidance of the problems in this article.
The last auto purchase was in her name with me as the co-signer. Didn't change a thing, other than now she doesn't have to rely on me to establish her bona fides and avoid BS.
Some people want to change the world to suit their view of it; others accept the way the world is and lead more stress-free lives.
