It all depends on how well it is cared for. Most any car built in the last decade can easily go 200,000 + miles with reasonable care.
I have 217,000 miles on my 98 Contour, and I don't have any intention of getting rid of it any time soon.
I have no idea how well your car has been cared for so there is no way for me to tell how soon you will have another big expense.
