Used Cars: comparison of two cars, hyundai elantra, elantra

Question
which is the best buy BMW G.I.  $3900  or a 2003 Hyundai elantra? $4000

Answer
Well you did not state what year the BMW is, but either way, this is going to boil down to what you need this car for, if you are looking for a car that is economical, and affordable to work on, go with the elantra, if this is not what you are looking for, and you just want a really nice car, that is good, go with the BMW.
