[Shotimes] Clarification on: SHO cranking but not starting

[Donald Mallinson]

I don't think anyone has brought this up in a while, but 
remember that in (I think)1992 the SHO was built with a 
faulty starter for part of the year.  The starter would turn 
too slow to fire up a car after it got many miles on it, or 
sometimes when new!

Could this be a car that excaped the recall?  Or quite 
often, when starters go bad, they turn over slow.

Just thought I would remind some about a bit of SHO history.
