[3X24SPD]

Had a few of those Tyco & Aurora sets. Loved them as kid. They didn't survive. Lasted longer than those Kenner SSP Racers going over the cliff with M-80's in them though...

I do still have the Dodge Scat City 1970 Challenger Drag Racing Set though, with the little 4-speed shifters.

Related, and waxing somewhat nostalgic, I recently purchased a modern slot car set for sale on the Hammacher for a "dueling mustangs stunt loop set". Google it, it's a cool setup.
It's a cheap gift to really make a kid's Christmas. Even a big kid.

I thought nothing would ever top the present that my dad gave me when I was 14 and we were just finishing up building the 302 motor for my 69 Z28.
I bought the car without a motor- and we built a 302 for it the old school way with a 327 block and a 283 crank. I sure do miss him.
My dad wrapped up the oil pan we needed for it- and put it under the tree.

When my daughter was about 13, she bought me a vintage Evel Knievel Stunt bike. I put it on display at the top of the stairs and I look at it every day and just love it. What a great kid she was to buy me that.
