With a monthly salary of $1,800, maintaining a car can be quite
a stretch on your resources. A more comfortable salary will be
$2,500.
I'm sorry to say this but it really irritates me when I see
sentences like this. It should be "Will I be able to afford a car?"
You may be eligible to purchase a car but the crux of the matter
is, can you afford it? Furthermore, it should be "Am I eligible for
...." and not "Do I eligible for ...."
