If you're a fan of Toyota, in addition to the Corolla previously mentioned, a late 00's Prius would be a good choice. Not too many of them with that few miles on them, but they are very reliable, so even 100k+ examples should get you good reliability. Likewise, the Toyota Yaris SEDAN (it's larger than the hatchbacks and in generally larger than an Echo) is a good economical choice. A little older and cheaper would be the 04-06 Scion Xa and Xb - they actually share some parts with the Echo. The Honda Fit could be a good choice as well, especially if you value having more versatile interior space to haul stuff around. To the safety concern, the Prius would be the safest of the bunch; it was a more upmarket car with more safety bells and whistles than the others.
As a side note, if you're buying your parts from the local stores, you can always google "advance auto parts coupon" and find a 30% off coupon; order your part online to pick up in store, then drive over to the store and pick it up. That's almost without fail cheaper than autozone or oreilly; occasionally even cheaper than rockauto or Amazon parts.
