Scalextric 1/24 scale stuff, made for only two or three years in the late 60's, is among the rarest of vintage slots. The cars, especially the Lotus and Ferrari, in complete shape are beyond expensive. The only other two cars made: an Alfa Romeo and E Type Jag, are a bit less expensive, but still a pretty penny.
And the 3 lane, true 1/24 scale track, IF you can find it, can really be stupid expensive. I know, over two years I found about 150' of it, and don't want the wife to know what I paid.
Still...this is on ebay right now:

Now, I have this set. Not mint. Cars gone, but the track is all there, nearly new. Controllers there, box in good shape, all paperwork in there.
Tell you what, if you're considering THIS set...I'll find and buy the absolute best examples that one can find of the Jag and Alfa (came in the set), and sell them AND my otherwise complete set to you for a mere $125,000.00!!!! You'll save nearly 2/3rds of a million dollars!!!
And I would throw in extra straight and/or curve sections (your choice) for just $8,000.00 each!
Takers? Anybody?
