Help me find this toy please

[MyBrownEyedHandsomeBoy]

It was either last year or the year before I was in the entertainer and I remember seeing a toy being demonstrated and it was small cars on a track and they were going up a slope, automatically climbing up it. Then they went round a track and I remember thinking when my son is old enough I'll get him that.
I can't remember what it was... possibly hot wheels?
Does anyone know what I'm on about, and if so please can you pop a link to this toy as I can't find it when I'm searching for it.

Thanks in advance

Could it be Glow Tracks?

Is it like this but with cars?
I think they're know as "Penguin Stair Climbers" so you might be able to find a similar one with cars.

Similar but It was definitely cars. I'm kicking myself now, should have taken a photo!
I have hot wheels in my head but cannot for the life of me find it!!

Is it this? Hot wheels city roller coaster.

Personally, I’d wait until the new year - not many people will be looking to move right now given how close we are to Christmas!
It’s very possible that a sale can complete in 8 weeks but do you really want to be moving house on Christmas week?

Back in about 2014ish, my friend was desperate to move before Christmas - they marketed early October, agreed a sale within 3 weeks and they completed on the 23rd December! I’d hate the stress personally…
