I don't know production figures off the top of my head, but the V8s outsold the V6s by a significant margin. Truthfully, the V6 was a hard sale because the EPA mileage was only 1-2 mpg higher. It came with a significant performance hit and also was only available in the lowest trim level. The V6s, for example, didn't have an electronic message center(gas mileage, DTE, etc) and don't have the heated/cooled seat option(present on nearly all V8s).
For "field spotting" look at the LS badge on the right rear of the deck lid. The V6 models simply say LS while the V8s say "LS V8." Of course, because this is just self adhesive chrome lettering, all bets are off if the car has been wrecked or someone has messed with the badges.
The one V6 variant I'd probably buy if I saw one is the manual, which I think was only made in 2000 and maybe '01. These are legitimately rare.
BTW, I've hinted at this, but for the prospective buyer I would suggest limiting the search to 03-06 models.
Under the hood, the '03 model got rid of the problematic hydraulic fan and replaced it with a conventional electric fan. The V8 picked up VVT, which added a fair few ponies and a decent amount of torque.
Externally, they are not that different but the '03 models replaced the "fluted" rear tail lights with flat faced ones-a change that I think complements the lines of the car very well.
Internally, the car got perforated leather all around. The front seats picked up heating and cooling on V8s(the 2000-02 only had heated seats). The seats actually have a really nice feature that I've not seen on any other cars-pushing both buttons at the same time locks the heater/cooler in "auto" mode-it heats and cools the seat based on what the climate control system is doing. All models pick up an electric parking break. The V8 picked up a select-shift shifter that actually works really nicely(its only limits are not starting higher than 3rd gear and it won't allow a downshift that would over-rev the engine-otherwise it does what you tell it to do).
There are a few trim packages to be aware of also. My car has the "Sport" package. In addition to slightly stiffer shocks(yes, they have a different p/n) all the bumper trim is body colored, the interior trim is brushed aluminum, and they have a special 17" split 7-spoke wheel. The LSE package makes all the trim body colored and has bold, chrome 7 spoke wheels(all 2006 LSs were finished in the LSE package).
BTW, '03s and very early '04 m/ys had rain sensing wipers. My January '04 car does not have them. They are a bit devisive-I've known of folks who swear by them and others who disable them.
