A Nissan bit your Taco?
That really sucks dude. I can't believe you didn't exchange info. ALWAYS exchange info in any accident, even minor. It always looks like nothing whenever you're at the scene because you're head is rushing with a lot of different things, and you may see the biggest dent but miss all the minor stuff, but then when you get home and examine it you find more damage most of the time.
At least you got the plate. Post some pics.
ALWAYS ALWAYS ALWAYS!!!!! get that info. its a safe keep even if nothing happened. also get witness info if possible. soooo many people get screwed this way. for all you know he can turn around and say you hit him!
