Which Macbook laptop for a car designer?
I am in high school and this year I will be attending a car design class, and I heard that some design schools require you to buy a Macbook, so which Macbook would be best for an amateur car designer? I also have a tight budget.

You're probably not going to need a computer to do car design in HS. Besides, the CAD software you need could cost upwards of $1000 by itself.
Many universities though can get it for cheaper. I'd wait until you enter a college or university before you worry about buying a computer.
