as long as you feel that is an afforadable part of your budget AND you love it so much you don't want to give it up.
Of course it is your call, as you know. Since it sounds like *immediate* cash or repair issues are not the problem, you have some time to weigh all your options carefully, and you will come up with the answer right for you. You have a nice sounding car which should bring a nice price at the right time and place. IF you decide to sell it, don't wait till you are in a crunch for $, moving or something. That way you can wait for the right buyer that will pay a strong price if it takes a little time to move it. And that almost guarantees that the new owner will care for it too, which is a nice feeling as it rolls out the driveway. Not to mention the nice feeling in your bank account. :-)
