hey bro, i was in the same boat as you back in 2003. I am from Delaware. Got acceptance to King Edward Medical Uni (KEMU), graduated this year.
My advice, wait for your final acceptance which will be in October or so, then worry about a car.
If your going to KEMU and you live in Sargoda, and IF you don't have any family in Lahore then most likely you will be in the KEMU hostels(dorms). Wont be needing a car at all to be honest, its a 5min walk.
IF you do have family in Lahore then go for the Carolla or Civic, which ever you like. 20K is more then enough.
I have an 05 altis (in 05, to me it seemed that the carolla had a better build quality compared to the civic) Right now they seem about equal.. But what ever car you do get, make sure you get Insurance, its different then the states, but highly recommended here.
let me know if you got anymore questions.
