My other strange experience occurred approx a couple of years later. I used to accompany my dad to RAF cricket club matches which were played at Vine Lane Uxbridge.
One day I was exploring the grounds near the main road when I noticed a large black car coming up the road. This is going to sound ridiculous and will probably appear to be a flight of childish fancy but the car was identical to KITT from the TV show 'Knight Rider' even down to the red scanner on the front. I remember, even at that young age, thinking that this is impossible. That it is only a tv show, but I was and still am positive that is what I saw.
I do not recall any sound at all from the car, not even engine noise. Also the windows were dark tinted. The car then turned on to a gated road which my dad later informed me was Ministry Of Defence property.
The only logical explanation I can think of (other than an over active imagination) was that some MOD emplyee was a big fan of the show and bought a replica to show his buddies.
