81 el camino value

[rsz71]

Thanks for the membership. I have the chance to buy an 81 Elcamino. Body is straight, new Cortez Silver paint, new interior (door panels, carpet, seat upholstery), 350 with Performer intake and Edelbrock carb., side exhaust, rebuilt M-21, 10 bolt with new 3.73's, Eaton, and axles, a/c, and some other.
Can y'all give me a realistic value on this El Camino? Hopefully I will buy it and become an official El Camino owner.
Thanks
Rob
