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
