Die Grinder or Air Saw or?

[JMarsa]

I just picked up a parts car and I need to cut the quarters off of.



I thought about using an electric reciprocating saw but since they have a low strokes per minute I figure this would make the cut line wavy. So it seems an air saw or die grinder would be the better choice. I'd take it to a shop to have it cut off but it’s not worth putting back on a trailer.

Recommendations and thoughts?

Thanks,
