Buy.

The first two were actually bought for me (#1 a clunker, #2 a HS Grad gift). The third was sort of a half-and-half deal, dad bought it to replace #2 and also as an early college graduation gift but I had to take over payments upon graduation/FT employment. Last year, I bought #4 and I couldn't be happier with it! I traded up 4 years and only increased my payments by about $30.
