This is funny, I just bought my Bonneville and my friends keep saying it'* an "old man'* car"! No, they're not car people, but a little perspective from the uninformed, who would never consider a car like ours.
All I can say is the resale value of the Bonny appears to be the highest among ANY domestic vehicle. No other sedan holds its value better except maybe the Town Car and that is because they are in demand for airport car services.
Finally, my wife who only likes sporty cars (turned down a Lincoln MKZ to keep the Bonny) thinks the Bonny a sexy car.
