I can't remember if my first transformer was a hand-me-down (from a family friend) or was bought in store back in the late 80's.

If it was a hand-me-down it was a broken and armless Powerglide (who I have since lost).
If bought in store, I remember being with my mum when she bought me the Throttlebot Rollbar at the local Woolies supermarket ('87/'88? I was about 4 or 5 years old).
I prefer to think him as my 1st because I can still remember picking him from the shelves and always had more nostalgia value. I always like jeeps, Hound was one of my favourite characters and Rollbar was the closest I could get to getting him. He always substituted as Hound in my playtime adventures

And the best part is other than a few scratches on the bottom, he still has great stickers, rubsign and a working pullback motor
