I'm actually inclined to believe it. Not because of any evidence, but because in UK parks, extremely few coasters are actually scrapped when they are removed from a park. They tend to be relocated. Have a look at RCDB. Most coasters marked with a dash in the status column (indicating that it didn't show up at another park) are shown upon closer inspection to have been sent on the travelling fair circuit. If G-Force was to be scrapped completely, it would only be the fifth UK coaster in history faster than 45 km/h to meet that fate (joining Corkscrew at Alton, Cyclone at Southport Pleasureland, Scenic Railway at BPB and Skytrak at Granada Studios). The 32 other dismantlings of coasters above that speed threshold (admittedly, some of which were the same coaster multiple times) all saw the coaster pop up somewhere else. As did most dismantlings of smaller coasters.
