My car with the following additions/changes would be sick "RARE".

FJ6 intead of FF4 +$14.05
V1X instead of V1F n/c
4-speed instead of automatic +$194.85 - 227.05
add the "performance axle package" +$102.15
add a sunroof +$461.45 - 83.95
add rear window louvers +$91.10

if the Air Conditioned - T/A hood'd - spoilered - 383 R/T wasn't rare enough .....
you could've ditched the A/C and sunroof from the fantasy car & bought a loaded HEMI car.

-- forgot to add the rear shoulder belts +$26.45 to go along with the existing partial horn ring



GG's "white book" shows 114 Challengers & 82 Challenger R/Ts with SUNROOFs.

Any super knowledgable Mopar head know if it was possible to have a 70 or 71 Vert with an H5 (Cloth & Vinyl Bucket Seats) interior? I always thought this was an option but I just looked at a 1970 Dodge Color & Trim Book Challenger and it indicates that this was not available for a Convertible. And now that I think about it - I cannot recall seeing an ebody convertible with Cloth and Vinyl interior... Assuming it was possible my rare build with start this way...
