Well (knock on wood) haven't had any problems. When I had the oil changed, the service man mentioned "replacing the valve cover gaskets". My DDs boyfriend (who is pretty knowledgeable "said it looked okay") but I am going to take it to DHs friend who is a mechanic, to look at it.
My vehicle is a Nissan Xterra, so "NO" it doesn't get good gas mileage. I have decided not to get a new car just yet, its been nice not having a car note the past few years. Maybe I should just rent for piece of mind. It will only be DH, DS and myself going (end of May,first of June), so don't need a big car. I hope I can find a discount. It just seems like the expense for this trip keeps growing. Thanks!
