You forgot to mention
Choose a car which has all body, interior and finishing parts intact otherwise the car becomes a moneypit - finding interior pieces for a B12 or B13 is a nightmare itself now.
The best built was the B13 as its the last of truly robust built nissans (when nissan proudly used to fly their flag on their publications and used to write below it NISsan SANgyo)
but only if one can find a specimen that hasnt been mangled up by desi ustaads and cheapass owners.
