Let me throw a total curve ball, and offer up the Corvair.
I didn’t make any attempt to identify low cost quality Vairs - but there are a ton of them out there. You can get Corvairs ridiculously inexpensively. I bought a 62 (early model) in really good condition for $2k. Most of the pricier ones will reflect body work and paint. If you can accept something rougher, you can get a solid daily driver well under $5k.
What a fun car to drive, and ridiculously easy to work on yourself. You could tear the whole damn thing apart and put it back together w/ a set of box wrenches and a phillips head screwdriver!
You may prefer either early or late model style. Early model is from 60-64, late model from 65-69. Tons of manuals out there - 4 speed only. Verts will definitely be pricier - and trickier to buy given possible hidden rust issues and the unibody construction. Forget all the Unsafe at Any Speed bullshit - they were no less safe than any other cars at the time (tho all will be less safe than a recent car). And as of (IIRC) 64 they had incredible suspension - shared w/ the Vette.
If safety concerns you, get a hardtop and install shoulder belts (very few came with them - much more complicated to install in a vert.) if you get a 69, you can get a telescoping column and headrests. Tons of parts available. Easy to customize. Tons of space - big trunk in front, and in non-verts, rear seat folds down.
Sure, only 110hp at the pipe, but w/ the rear engine, a slow car that is tons of fun to drive fast! And you can’t beat the looks and comments you get driving it around town!
