Perhaps it's a sticker, like a truck club logo. Perhaps it's the glimpse of an intercooler. Perhaps it's a gauge cluster, or primer spot, or some other subtle characteristic that sparks your curiosity. I had such an experience on the way to work the other day. The Chevy Colorado in front of me sported this sticker on the back window (as I know it's hard to read in the picture): "Sponsored by: Under Construction. Sweat and Tears." Now, any vehicle that says "under construction" sparks my curiosity. This truck, however, didn't seem to have anything done. My excitement was fading until I passed it and caught glimpse of a 22" badge near the front wheel well, which at that moment was stuffed with stockies. So yes, I will be on the lookout for this Colorado. It may be nothing, or it may be on its way to something crazy.
