I will be going to the Philly car show this weekend. Indoor car shows are pretty challenging. You have to cope with harsh lights, dim lights or just bad lighting. Sometime there is no room to back off to take pictures. Flash is of course out of the question. It has never worked for me. I have a wide variety of lenses on my film EOS. From wide angle, to the 50/1.8, 85/1.8, 75-300 etc. I suppose I could just take one of my fast rangefinders, like the Hi Matic or Canonet but manual focusing sometimes is too slow. I have been to this show before but never hurts to ask.
