Should I get rid of my 10 year old van?

I have a 2003 honda odyssey van base. It has only 86000 miles on it, but I am recently thinking of replacing it. There are many expenses coming up, that would be very costly for its value. The exterior is in fine shape, but the interior is in rough shape.(two torn seats, and many stains.) The main reason why I have been deciding to replace it, is because winter is coming up. The van has some skidding problems, and sometimes has problems starting in the winter. Sometimes it takes an hour to heat up. I feel it is easier to replace the van, but what do you think?
