Hi there.. here is some info for you.. from "Squadron's U.S. Armored Cars in Action". a good basic resource on these.
this is just part of the section about Europe.
"By the time the Alies hit the beaches in Normandy the M8 had become the primary vehicle of the Reconnaissance platoons armored car sections."
and so forth and then...
"The M20 was used in a utility role by the recon units and headquarter sections. "
From the gist of my reading in this book M8's were used to probe and find weakness's in german lines. and when they found something too big for them their high speed was used to disengage.
From my understanding of the kits Tamiya v/s Italeri the Tamiya ones are generally better molded
Tamiya M8 review by cookie seawell Italeri M8 review by cookie seawellI personally have both Tamiya kits 1 of the M8 and one M20. I have done the M8 and had no reall problems at all. the only grip I had was I left the drivers compartmant open and the inside walls of the area were basicly bare so I added the equipment racks and equipment inside there.
the only other thing I can add is be carefull glueing on the wheels of 6 wheeled vehicles as it can be easy to get a wheel that sits on "air"
The M20 kits of both companies are built on the same basic model of the M8 with the turrent spruce exchaned for the new one for to build an M20
