Yes, I would definitely ask permission when going into a dealership. Another though is to go to a dealership that deal is classic cars. You could probably get some pretty nice detail shots that are much tougher when you have crowds of people around. I'm glad you enjoyed the show. I'll make a Part 2 in another thread so as not to overload one thread with images. There are some older cars you may like. :)
