Travelling toward Ipswich on the A14 this afternoon were 7, R32's.
Assuming you mean Golfs not Skylines? There was a German only car show - Low Collective - at Stoneham Barns on Sunday which is probably where they came from.
A bit late, not a car but an awesome spot on 4th Sept :
Hawker Hurricane from 501 Squadron V7497 coming over low at Elmsett (while I was looking at cars) and landing , taxiing and shutting down. Made my day.
Three spots on Friday 14th September between 6pm and 6:30pm around Dereham. Yellow Lotus Esprit, red new-shape Mustang & a blue 70s American muscle car, I believe a a Dodge Challenger. It sounded glorious!
