As was said on this thread back in 2008, a Holy Grail is the one and only kit that would make your life complete. In my case it's the 1966 Plymouth Valiant Signet promo, one of the rarest Mopar promos. I had never seen one in person and had an eBay search active for one. Wouldn't ya know, the only times one was for sale was when I couldn't afford (or at least in good concious) invest in something expensive.
The last time I saw one on eBay was when I was in the middle of moving from NJ to PA. I was carrying two houses and finance were pretty tight. And of course there it was for $400 Buy It Now. So I closed my eyes and hit that button. It was mine! Feeling a bit guilty but I had my holy grail.
At the same time I was parting out my '63 Studebaker project that suffered from terminal cancer. It just wasn't worth trying to fix. I had offered it for sale on both eBay and Craig's List for prices starting at $2500 and all the way down to $900 without a buyer. I had $1500 in NOS and repro parts alone! So I had sold over $3000 worth of parts off this car. In the end I had a carcass with no body parts, but a 70k drivetrain still in it. I didn't want to send it to the crusher so I did one last ditch ad onto eBay offering the drivetrain for $500. Imagine my surprise the next day when my email read "You've Made A Sale". Someone in North NJ had bought it to put in his 1940s pickup. So by the time it came to pay for the Valiant, I had the money in Paypal to pay for it. Nearly free!
This is a photo of the one I own. My modeling life is complete. I don't want for anything more!
Nice ! A bit pricey for my tastes , but I've spent almost that much on a model I really wanted , so " Why not " !
