IVIV semi-obvious Plymouth, p.31

[Mark Kohut]

with an E-for-Exempt: Tax exempt.
"Investor E(Exempt} pays no tax"--IRS [google]

Another Pynchon Plymouth...they are in V. and
elsewhere. Also in Chandler noticeably, usually by
well-off heavies, a fitting car.

"No one calls my car a murderer, man"....Notice it
is Doc's California identity that kicks in with this remark,
not his hippieness.........

some great comic lines follow, imho.

Cars are what are often loved in Pynchon's works, rather than 
human beings, as a number of plisters have recently reminded us
re Rachel Owlglass and others....
