A few more grand ends up being a lot of money, especially if you're young. For example...

When I bought my LS last year, I had $4500 down. I still had to borrow $15,800 and had a payment of $325.14 for 60 months.

Buying a WRX without ANY options is $24,720. That would turn out to 414.84 for 60 months.

A few grand makes a difference.
