Hi Chrissie
Quesada is NOT what you would call a Spanish town by any means. There are lots of Brits, Dutch and German residents, although of course, there are Spanish residents too.
It´s a ruddy nightmare to drive around because there is absolutely no rhymn or reason to the layout and you can easily get lost in the maze. The main streets are very, very busy.
There are lots of facilities - clubs, sports, bars, restaurants, schools, shops, etc. - so depending where you are in Quesada (its pretty big!), you may not need a car.
Personally, I prefer the villages around Quesada - Rojales, Benijofar and (my favourite) Formentera del Segura.
