I would go with the 220 units.
I have a Hobart 220. Hobart is Miller parts and consumibles .
Crank it way down to do your little sheet metal work and still have the capability to do serious (fun) welding.
I have used my Hobart 220 from everything from floor pans to building complete car trailers.
This is just me----- but, once you have a 110/120 unit you will wish you had a 220.
Example: welding through rusty/scale to obtain an even penetration is nearly impossible with the 110 units with out having to waste time with grinders/wire wheels and you'll only be able to do short welds (penetrating welds).
With a 220 unit you'll be able to get the heat up (stay up) to blow through rust/scale and still lay down beautiful welds--- without wasting hours with a grinder/wire wheel.

^ yes and no.... yeah a bigger one will heat up alot quicker, and hold heat... but in bodywork you DO NOT want this... frame work, yes... or any other type that is more of a solid structure.. but def not on panels.... any panels... it will warp and cause you to have a much bigger body shop bill or headache with labor in fixing the warped panels.....

if you are doing alot of fab work, on various sizes of metal with it averaging 1/4" then yes I HIGHLY recommend a 220v welder... if you are just repairing small things on a car... 110....

Mainly i will be doing a couple spots on the floor, a couple in the wheel wells and i need to fab up a 77 rear end. I may also have a spot on the quarter to do. If i was using a 220 would it be okay to use as long as im taking the time to cool the panel down between welds?

yeah... you can set the heat and wire speed right and do the same as a 110....just go slower.... a cold wet rag... or cold air will aide in the cooling....

I used compressed air for cooling between welds.  Worked well.

a 115 volt  20 to 25 amp breaker at the box is fine for auto body.    dont use it on a 15 amp breaker , you'll cook the board in the welder.  unless the manual states a 15 amp breaker is fine.   

when weding auto body, you dont hold the trigger .  it 100's of spot welds.  and skip all around the patch or it will warp.   

if you use gas ,  use 75/25 mix.   it'll burn cleaner then argon.

And I paid about $120 for my tank and $30 a fill up from a local gas supplier.  One tank will last a while.  75/25 mix as Doug stated.
