Ok, I'll throw mine into the ring...
1970 Lemans Sport convertible, Palladium Silver (Maaco repainted over same color by previous owner, decent paint but not great.)
We bought it in 1996 from a guy in Petaluma, Calif. (a small-time local used car dealer) who had bought it from the original owner (papers seem to validate this claim) - the original owner was supposedly a Fremont GM factory worker, car was built in Fremont and according to PHS it was sold by Cunha Pontiac in Berkeley.
After using it as a daily driver for many years, it sat in my workshop starting in 2003, due to a variety of factors. I pulled the front clip because the engine compartment was a complete mess (see first pic in gallery) and planned a firewall-forward resto. Though a mess, everything was there - all original as far as I could tell; numbers-matching 350/2bbl engine and TH350 transmission. All original parts/accessories were there (a pleasant surprise.)
Then I decided to update the front suspension and front drum brakes, and then... well, long story, but let's just say I put the project on hold a couple of times.
I had it all together about five years ago but the 455 build I transplanted didn't work out due to abject stupidity on my part so it never made it back on the road. After that, I let it sit for years due to various distractions, but I recently re-assembled the factory 350 "quick and dirty" and stuffed it back in to the bay. (Runs great, by the way...)
The goal was (and is) to introduce 'reversible' modifications that will improve the 'driveability' but won't destroy the value of the car in the future. This is a daily driver and not a show car so the priority is practicality above other things, but still trying not to deviate too far from original appearance... perhaps with the exception of stance and wheels/tires
Now that the kids are up and out, it's time to get the old girl back on the road. (Shhh... don't tell the wife but it's our 30th wedding anniversary late August and having the Lemans fully functional is my present to her...)
So, just got it registered and insured the other day, followed by a few shakedown cruises. Handling and brakes are much better than before. Next improvement is to choose new wheel/tire combo..
