Mine's getting towards that mileage now, and although I'm not overly concerned about it being done bang on the recommended mileage, I think I will want to get them done before I start putting higher mileages on again next summer. My previous thous all went way over that mileage without a check, and there were no problems, so it's not something you have to rush to get done now, but I'd say it does look better in your service book if you ever come to sell, if everything is stamped as per recommendeds.
