The very word "useful" with "useful cars" indicates "there are not so useful cars out there, that's why we bring you useful cars"...its a bit of a strange brand. A customer will naturally consider the purchase of a car, and decide themselves if its useful, without the influence of a name like "useful cars"...I feel the word is unnecessary

Also, running under "useful cars" as a brand...isn't so interesting. Little value, in my view. Reg fee territory, but hope you get something while you have it. Sorry

thank you for this analysis

@jhm Indeed. It's a strange, artificial word to use in this sense. It's like saying ''four-wheel cars''. All cars are useful.
''Cars'' is a very popular word, I know, and it's hard to find a good match, yet still some better words will be available (also, you may want to check some GEO+cars, but GEO normally you sell cheaper, like $XXX. However if you are a total newbie, probably I'd stay away from GEO for a while).

I agree with what jhm said. "Useful" kinda goes unsaid.
Is there a big market for useless cars?
