    Re: tube vs. donor frame

    production frame a.k.a. fiero (what else is used anyway):
    - dirt cheap
    - electrical and mechanical and suspension is all done and installed
    - tested and pretty safe design, for the most part

    - heavy
    - certain size, like it or not
    - suspension is generally low end and not very high tech
    - transverse engine setup, no choice really
    - complex and messy procedure to stretch the frame

    tube frame:
    - if well made, safe and light
    - whatever size, shape, and suspension you want
    - custom fits body you have
    - whatever engine, where ever
    - replicate a real chassis if needed

    - most are amateur half-assed jobs, prone to rust and bad welds
    - design might be unsafe, and you won't find out, the surviving family members will find out :-\
    - can get very expensive very fast, from materials to labor, and who makes it
    - if badly designed, chassis flex or rattle can make for a bad driving experience
    - race suspension can cost as much as chassis itself
