Looks like no one wants to bell the cat here! An actual appraisal would be 150 to 250 due to the relatively common car models and their colors. Much would depend on the feeding frenzy at the time of auction and the phase of the moon. I swear the full moon brings out the crazies and their cash. LOL. I feel that this set is a keeper, for what it's worth.
As previously stated by Jeff and myself, this ones really about the packaging. Although some collectors dig the fancy box art, the plain brown wrapper is far more durable. Looks like the individual inner boxes and their typed lables are in mint shape with one exception. Also it looks like the controller boxes are missing. The super bonus is the car cases themselves, complete with their labels and apparently uncracked. Many times they are cracked, crazed, partials, busted or just AWOL.
Unfortunatly the cars are not examples that the wacko collectors are gonna rev up the bid list on. If a guy chooses to poke in cars of the correct model, but snazier more desireable colors later, so what!? It makes a better display. Back in the day it was all a crap shoot anyway. Ya got what ya got.
As for the car bodies, a gentle bath in warm soapy water. Letem' soak a bit,then gently use a soft, kids toothbrush to massage the crud away. For really stubborn stuff a little cleanser (comet, **** and span, whatever) may be used carefully. Keep in mind that cleanser is abrasive and will start to erode silvering, or thin Tampos (graphics) if your not careful. For a finish I use Megwiers#9 Scratch and Swirl remover. Gently!
The turq Cobra gt will clean up nice. The guardrail burns on the rear quarters might need a little cleanser. They can be stubborn. A touch up of silver highlights and your done.
The white GT 40 should have the rocker stripe in silver. There are a zillion variations of this Ford so I could be mistaken. Ya got lucky with the busted glass, as the A pillars usually bust with it. I've got a replacement should you choose to repair it.
The tan Porsche 904 looks like it just needs a bath n buff. A lot of people pooh pooh this body as cheap and ugly, but they really were sturdy and have stood the test of time.
The Chappy got brushed on the hood and rockers. The runs up the door seams can usually be picked out with some patient tooth picking. Were it me, I'd delete the botched #2 on the hood and rescuff the rocker and touch the car up judiciously with black and silver where required as the originality has been long ago forsaken. Are there holes for the roll bar? Be very careful around those enginge stacks!!!!!
Have fun, take your Sis to dinner. She deserves it!
