My personal opinion is to take your time and find a certified car from a dealer that you can afford, even if it means doing what I did; waiting until I could afford one new enough to have a meaningful warranty.
I'm a bit older than you, well, hell, I take that back, I'm a bit older than dirt
but you are buying a third car as a toy. As hard as it is, listen to someone who learned alot the hard way, don't rush into a possible disaster.
Gotta have that always, and I mean ALWAYS came back to bite me.
