I am pleased to say that my last girlfriend could change her own bulbs in her car... and without fear of mussing up her nail polish (which were ALWAYS impeccable) or getting close to having dirt under her nails, much less on her skin.
Yeppers, she was definitely a do-it-herself kinda gal at times like those.
I would also be willing to bet she would have changed her own oil and even tuned up her car if she had a manual to go by.
