I have maybe 100+ Hot Wheels and maybe 20+ Matchbox. Also other mini cars - ranging from 3" - 10". Mostly Ferrari, Lambo, and Porsche 911's. When I was a kid, I'd buy them, strip the paint down and redo them swapping wheels/etc., repainting them and adding spoilers. Plan was to be a 911 designer but didn't pan out. Hot Wheels is classic but I always liked the foreign models by M.B. and always felt M.B. had a bit better build quality.
What I love doing is gifting people their exact car. I've given coworkers a black Vette, a black Tesla, a vintage burgundy Stingray (was green, but I repainted using nail polish), gave my kid's 4th grade teacher a blue/gray Toyota FJ (the larger brand of 3-4" cars you find at Rite Aid/CVS/etc.), and our work accountant a white Audi Q5. I have one of those larger ones for my silver Benz daily driver, and a Hot Wheels of my weekend car (silver w/black rims). I even keep one in that car velcroed on the dash. I used to have a 1988 Ford Mustang GT in dark/light grey and had the exact same mini car in some other brand (Maisto?). I also gifted a coworker a black P. Cayenne SUV and my boss a gold Range Rover. I could never find a good 1999 Cherokee in emerald green to match my Jeep.
And no, I don't keep them in the box. All my cars get played with, rolled around and all corner great on my desk and sound awesome! I have 2 boys that also share my love of cars, both real and mini, but they know not to touch daddy's collection! In my old house, I had them on display in my music room. My current place's music room is still under repair, though, so most are sadly sitting in a bag just waiting to get out again.....
Also, my bro-in-law's new wife's aunt's 2nd hubby is an old white guy who used to work for Mattel back in the day. He was in charge of developing 2 lines - he was an operations engineer - the Barbies and Hot Wheels! I saw him at Xmas last year and we shared great stories. My weekend car is my dream Hot Wheels and even has a "Hot Wheels" sticker on it....the dudes love that!
Matchbox! Had both as a kid but Matchbox was better built and had lots of cars modeled after real cars. I liked Hot Wheels but they mostly had factory cars that were modified and painted to look like something else, plus they had a ton of made up cars that didn't even exist. Even as a kid I realized this fact!
For a grownup collecting old toys - Matchbox for sure. For a kid - whatever floats your boat. A year after getting rid of the hotwheels track my son never played with, he started getting into with a vengeance. Right now it's about all he wants to watch on youtube. We found a used Super Ultimate Garage for $30, and that's Christmas this year.
As my 5 years old grandson says... "ALL of them"! Ive been playing with toy cars since the mid 60's and have never stopped. I sold a little over 30,000 Hot Wheels in a single sale one time because I thought it might be getting a little out of hand... ! I still maintain my collection in my den and garage / workshop but much more manageable now. I only collect 1:64 racing sports cars replicas (with a little drag racing section) so it's easier to manage. I still enjoy building custom cars but I have been so busy the last few years that has slowed a bit. I really enjoy my toys! As an example, this is my collection of 1:64 John Greenwood Corvettes raced during the 70's. Lots of brands, some custom made some modified and some factory...
Both. I have a ridiculously large collection. I have a large collection of drums too. And guns. My all time favorite from my Matchbox is a yellow field car pulling a yellow Honda trailer with a purple Honda motorcycle.
Over the summer at my dad's house, we rebuilt a shed on his property that had been hit by a pretty tree limb. In the corner of the shed I recognized a good sized box... but could not remember what was in it.
In the box I found about 20 or Hot Wheels, Johnny Lightning and Matchbox cars (as well as a few others) all from the late 60s early 70s.
Most of the were in OK, not great shape..not from years of storage, but from me... I guess I played hard with them.
There were a couple I could not find, one of them was the Red Baron car which would be worth a little money.. I'm sure it will turn up.
Still have a lot of the track setups in the attic too!
I was an avid Matchbox collector when I was a kid. I passed them on to my son who decided it was better to play with them than store them away in a protective case like I did. However, I liked Hot Wheels from the aspect of racing. I still have some track and the housing that propelled them through each lap.
