I agree that it is a very fair price
For some there will be the issue of registration, maybe you could take your car to an engineer and determine the gap between what you have and what someone would need for ICV reg.
engineer
If you have used compliant seats/lights etc then the gap may not be so big and the car you have might compare favorably against a turnkey minus.
It might be up to you to educate prospective buyers about their options to get your sale.
