QUICK! Anyone with tips for shooting cars?

I've shot thousands of car photos and my friends seem to like them enough to keep asking me to do them...so I don't think I'm too bad at them...BUT...it never hurts to ask you guys...any tricks that work well for you? Tips?

I'm not sure if it'll be day or night, but most likely night...or both...but definitely night haha. I'm thinking of trying some long exposure shots by the ocean to get some smooth reflections off the water. I'm gonna buy a mini tripod tomorrow (mine was too big to fit in either one of my bags )...anyways...any tips/advice/idea/whate​ver would be appreciated

cheers,

PS: oh yeah...this'll be probably within the next 24 hrs...

I don't usually care much for night shots of them. Seen this?

You need to have a high powered rifle and remember to lead them on your scope!
