I haven't come across any threads that contain specs like bulbs, weight, tank size, fluid capacities, firing orders, CEL codes, etc. That's important information and it'd be good to have that info in one thread, or threads, for the different generations.
Maybe break the Off-topic section into non-car chat and non-corolla car chat.
