First of I apologize if this is a repeat, but I tried searching and could not find the answer. I am looking for running boards for my 2007 Highlander AWD V6. Is it better to get the one from Toyota? If so, where should I go to get them? Is it hard to install or just go to my local dealer and have them do it? What about other brands and models and what not? Price as well. I really like this car. Thanks all.
