A friend of mine got his old scalextric out from the loft which he has had since the 80's. We set it up and all worked ok. We decided to go out and buy some more track, but it worked out cheaper to buy a whole new set.

The new set was awesome.

The new track was better ( old track slowed down the new cars).
The new cars were double the speed and stopped alot quicker.
The new evo was 4wd.
went around corners alot faster.

We put all the old stuff back in the loft as none of it was worth using compared to how good the new stuff is.
