My wife HATES my car.

Yes.

My wife is semi-mechanically inclined. She owned an air compressor and several pro woodworking tools when we met.
I've found working air conditioning goes a long way towards her being agreeable to ride in my old cars. She also has long hair that doesn't work well with open windows. She likes the rear window design on first generation Barracudas and has said a few times that she'd own one if we could find an affordable, solid one (with AC).

We never have money arguments because we have mine, hers, and ours.

She has accused me more than once of running an out of balance rear tire on purpose so I can watch her breasts undulate at slow speeds.
