Good question KC

I second buying the windowless body shell. I recall in Unique cars one for sale for $6,500 in the early to mid 90's which I too thought was ludicrous.

I also recall as a kid (born 64) an article circa 73/74 in either Wheels or The Melbourne Sun where they costed building a HQ sedan completely from spare parts...complete engine, body shell etc. My figures are probably askew but the sentiment is the same. New car approx $3,400........ spare parts version close to $30,000. An early education on how expensive spare parts were.

I wonder what's really out there
