Nope you certainly aren't alone.
I'm a student too and spend far too much time looking at car stuff when I should be doing work. Like for now instance, I'm writing my dissertation (on car culture funnily enough

) and am currently surrounded by books and notes. I also have a design project due in tomorrow morning and yet I am sat on here looking through the classifieds

Money wise, I only allow myself to spend cash from working and savings rather than the loan, although I did have a maxed overdraft last year from fixing the mk2

Fortunately paid most of it off now.
No real advice to offer but student to student, I get ya

I've left the car at home now in a bid to keep it tucked away, out of site out of mind and all that. A super busy 3rd year means I have no choice!
