About a year ago one of the sometimes posters on this site found the need to sell his extremely clean and low milage used SVT. His family had grown and he felt the need to replace it with a mini van. His was unmodded. He knew that as nice as it was, he should get a good price for it. After asking a lot of questions here about how to market it, he found that the serious buyers, at least from southern California, read AutoTrader. I don't know if it as active in your area as it is here.
I also agree that it may help if you remove some of the mods and sell them seperately. Most definitely make sure that it runs right so if you have a question about the IMRC, replace it.
You want to be able to tell a prospetcive buyer "if you drive it, you will probably buy it".
