I would say that this domain is in the $60.00 - $120.00 USD range.
The keywords in the domain are spot on with the concept of a consumer looking for insurance, but I think that the words are reversed - instantinsurance.com sounds like it could bring a profit almost instantly.
I would say that it might be better to develop the domain rather than park the domain because you will not get much type in traffic or anything like that. instantinsurance.com is a parked domain, too, so you may be able to overtake it with a developed site.
On the other hand, you may be able to find an insurance company that is interested in buying the website because Insurance Instant sounds like the beginnings of a good brand name...
