Ya. Everyone here is right.
Your gf claims 900 per month for installments. She have not include
petrol, erp, parkings, summons, insurance, maintenance.....
And she is still with her old job which pays little. Very very
little.
50K is very little. And judging from your post, she seems to spend
a lot. Heck, I swear by end of this year, the money will be
gone!
Sorry to say... but I think, she will regret it very very very
soon!
