Buying a station wagon WOULD be proving my love to a woman! I'd show up with $1700 but with $500 of it in a different pocket. Look it over really well, test drive it, and after inspecting it more I'd offer $1200 if I thought it was worth getting. Then I'd fill the tank, drive home and legalize it and then go on a picnic at the lake...
Male or Female, IMO if you have to prove your love by selling and or by the car you drive, YOU are with the wrong person.
