I still haven't bought the Matra. It's due to an old bias. I heard how the real ones sounded after about 8 hrs at the Daytona 24hr. ( Like someone had thrown some pebbles down the intake manifold.) And I do realise that has no bearing on how the slot car would run.
My local track just got in the new Matra and I have to say - it looks even better in real life! (and yes - one followed me home) Can't wait to start turning some laps with it!
