I can think of a few. First of all, Probe seems cool (I like it, reminds me of classic 1950s alien horror shows and UFOs, which I love) and I hate these stupid, forgetable letter/number names! S-10, F-series, DS, G6, C6 and all those others. They are forgetable and have no character at all.
But here are (to me), the worst NAMES (NOT numbers or letters):
1) Dodge Aries (reminds me of an old man, not sure why)
2) Peugeot Partner (what does Partner have to do with a car?)
3) Citroen Jumpy (what the hell?)
4)Chrysler Saratoga

Here is the Best names:
Ford Windstar
Ford Expedition
Ford Taurus
Ford Probe
Hyundai Elantra
Hyundai Entourage
Ford TelStar
Pontiac Grand Am
Chevrolet Corvette
International TranStar

I agree with the LUV. Good name for a small sedan, but for a pickup?
VW Thing, is a bad name and very hard to use. "Hey baby, I just got done waxing my Thing!"
