<human>: Hey, PF!

So I'm new to this whole "adulting" thing. My fiancee and I owned one car between the two of us, a 2010 Hyundai Elantra. It got totaled this week in an accident, and we're now getting about 6.5k back for it (it was worth about 7.5k but they took out our $500 deductible and another ~500 in "existing damages" to the car-- mostly interior cosmetic stuff, but w/e). (And yes, before y'all ask, I already checked KBB and it's a fair estimate for what we get back, honestly.)

We have about another 1k from savings we can use toward the car, leaving us with a budget of 7.5k. We'd like to buy in cash if possible, and we're hoping for something reliable, decent on gas, and with mileage under 100k.

A few questions:
1) Is this possible?
2) Where should we look to get good deals from reputable sellers?
3) Any other general tips for used-car buying for two broke 20-year-old women trying to figure out how this whole thing works?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Car totaled, getting a fair sum of 6.5k back from insurance. Can we get a reliable, under 100k miles, reasonably efficient car for 7.5k in cash, and if so, how?
