Thanks for the ideas. I'll just tool around with some graphics programs for a bit. I need to get the images sharp on my PC before I even think of printing them.
I can't wait til I get the hang of this, though. I've already got visions of 348, 355, 360 Challenge cars dancing in my head. Or 250LMs, 250TRs, 250GTOs, 333SPs, 330P4s...oh man, am I ever opening a can of worms.
