2005 Miata 5speed with 102k miles. Owner is an older woman. She has agreed to sell it to me for $6,500. Car is stock as far as I can tell and it drives great. These are the issues I noticed: Oil is seeping from the valve cover and the soft top is falling apart with the rear window pretty much just hanging there. Is the valve cover leak a bigger problem than it seems on the surface? Location is Northern California where these are generally going for over 10k. Is this a decent deal or should I walk away? I’m looking to buy this as my second “fun” car.
