Guys, A bit of advice please and apologies if this advice is elsewhere on the site but I cannot find it. I am looking to do a DIY service replacing the oil/filter, air filter and spark plugs. Is there a walkthrough on here or does anyone have one giving me an idea of how to do it on my is200. I have done it on other cars but not this one so have a basic idea. I am unsure where exactly the oil filter is..!!! I have looked but bizarrely cannot find it. Any help would be greatly appreciated. Cheers
