I hate to cross the line on bad taste, but there is a guy at my office that says any car name that you can add "anal" to the front of it and it makes some sense is a bad name for a car. This might hurt the following vehicles just to name a few:
Explorer
Probe
Navigator
Intrigue
Excursion
Vue
Charger
Silver Mist
Silver Cloud
Liberty
Sonata
Accent
Fiesta
