To get anything that meets your crieteria and is still reasonable reliable you’d need to buy a restored vehicle from the '60s or earlier…and accept the foam coushions and naugahide seats. But at least the dash would be steel rather than molded platics (nice to bang your head against), reducing the amount of outgasing a wee bit.
But you’ll have to accept the realative unreliability and orneyness of carburators, and the lack of safety systems normal to today’s cars. And youu’d have to live with drum brakes that lose their grip when they get water in them and handling that’ll almost make you seasick. Watch the Retro TV Channel sometime. Watch the old 60’s cars go careening around corners, lenaing for all they’re worth.
The truth is that fuel injection systems are far, far more reliable and much better operating than carburators ever were. And modern handling, suspension, and braking systems are worlds advanced from the old cars. And if you have the misfortune of getting involved in a crash, you definitely would want to be in a modern car rather than a '60s car.
If you want to do your own work, would it not be better to learn how modern cars work? I can suggest some books to read if you’d like.
