70 L-S5 SS EL Camino WIW

[Bruce]

Hey Guys
I'm looking for some help here to try and place a value on this car.
It's a 70 SS 454 L-S5 El Camino, it has the numbers matching 454, M-22, 3:31 posi, PS, PDB, F-40, HD bat. front bumper guards, remote mirror, tach gauges, bench seat, non cowl induction, all tinted glass.
Fathom blue, white stripes, white vinyl top 5 original ss wheels, still has the origial tiger paw tire on spare. Original int, with exception of the seat cover being replaced in 88. Looks to have some touch up paint work so I can't determine how much is still original paint. The interior is near perfect condition for a car with 76K miles.
Not a scratch or dent in the bed it is in unbelievalbe condition. Car has no rust anywhere, and appears to have all original sheetmetal. Only changes under hood appear to be 1 heater hose and plug wires cap etc. Original upper and lower rad hoses, reverse lockout in place.
Original owner had the dealership install a Hurst shifter but the original muncie is with the car. 2 owner car with build sheet (LEEDS). Any help is greatly appreciated.
Thanks
