Personally, I employ the same philosophy with my slot cars as I do with my 1:1 cars. They may look good standing still, but they are kinetic art. I drive them until the wheels fall off, then I fix them so that I can drive them some more. Some friends call me T.T.F. (Test 'Til Failure!)

I "accidentally" got my first shelf queen a few months back, when I picked up the Le Mans Miniatures Audi R18 TDI. Lovely looking, but the mirrors and spoiler will break off if you just look at the car with both eyes open at the same time! Add a very heavy resin body and, despite Slot.It underpinnings, it's just not a runner.
I ask this question now, because I'm trying to build a class of late 60's F1 cars and I have the opportunity to get a Scalextric Lotus 49 Gold Leaf - Damon Hill.

These are now pretty rare: only1500 were made, and the current asking price is around $350 USD.

So as I ponder this, I'd love to hear your thoughts on collectibles vs. 'race-ables'!
Best,
