Hi there I don't mean to intrude so please forgive me if this is an inappropriate place to make a bid for some assistance but I'm a bit overwhelmed. I'm a student in the UCLA Writers Program and I am working on a novel set in Los Angeles between 1912 to 1934. I have found some wonderful resources on roads and vintage automobiles online, as well as through the Automobile Club of California and the USC archives. But... I wondered if anyone might be able recommend a resource for the layman that could help me keep from putting my foot in it when it comes to authenticity i.e. a resource with some basic facts on given models of the time like seating capacity, maximum speed, availability and popularity on the West Coast. For instance, right now I have my characters driving out to a construction site in a 1913 Ford Touring Car. But I'm not sure how many people I can fit in the front seat or how long it would take them to travel from Pasadena to Rancho LaBrea. Not to play to stereotype but I'm the kind of girl who never learned anything about cars except "ooh! shiny!" so please forgive me if I sound hopelessly ignorant. Many thanks for any help you can offer and for letting me drop in! Best, Leigh
