I've been a long time fan of the early Celicas. My first car was a 1972 Celica that was a hand me down from my grandparents, with only 30,000 original miles. The car from my grandparents was rusted out real bad, so my dad bought a clean 72 body and we swapped the drivetrain into it. (this was in 1989). Then I used the rusted car as a parts car. I wish I still had both those cars today! I have many fond memories of learning to work on cars with my dad and my friends on the Celica.
My original yellow parts car ended up in a junk yard in Moss Landing, CA area in the late 90's. The red car was sold to an individual where I lost track of it. I think we heard this also ended up in a junk yard somewhere in the same area. Maybe one of you have seen them or own them now? If so I have a lot of history on them obviously.
1974 GT I just bought, as found in San Jose:

(Ouch! Makes me sick. I wish I still had this. Little did I know these would become rare and the parts hard to find).
Anyways, glad to be part of the 1stgencelica community!

I like reading stories of members who had a Celica back in the early days and have pictures that document it. I have yet to post my history pictures but I have owned my 75 RA22 Celica since 1985 and it has gone through about three major changes since I first bought it. The same happened with me and my two sons when they were younger so keep passing your son those wrenches cuz he will love you for it in the future! My older son is now studying mechanical engineering and is doing really good at it and my younger son will follow but in electrical engineering. Just wait till you let him shift gears for you as you drive and push in the clutch, the ssmile will be priceless and unforgettable! 
And try and get him the Celica Hot Wheels car, the red one comes in racing decor. Just the dad side of me showing here sorry about that. So if you click on the following link you can see my re-introduction then click on the link inside that post to read a brief history in my original first introduction.
I said "Are you sure?" He said "YES". I said, well OK, but in a parking lot first. Before he tried I drove around with his hand on the shifter and my hand on top of his. After he got the idea, we went into a big empty parking lot and traded seats. I'm like, OH BOY I hope this is a good idea. 
I explain the way to drive, push the clutch, etc. So he starts to drive and I shift. We bounced around a bit from 1st to 2nd and 2nd to 3rd. After about 10 minutes in that parking lot I said Hey you want to go out on the road? He looked at me like I was nuts. 
I said go for it. So off we went. Within a few minutes we were driving on the main roads and he was shifting, with a little help from me here and there to get from 1st to 2nd (instead of 3rd where he wound up a few times). I gotta tell you guys, I don't know whose 
was bigger, his or mine. PRICELESS!!!
