Hippopotamuses

[Paul4978]

An eccentricity of Landrovers

[Beowulf]

An eccentricity of Landrovers

That would make for an appropriate collective noun for a group of Series LR owners 

And that reminds me, if you`re there Mark  , what did you think about my earlier proposal? - This last one might appeal to diffwhine, "a Range of Rovers"

[DogDave]

Given the smoke I'd go for a cloud of land rovers when the engines are running.

[diffwhine]

A range of Rovers
A cloud of Land Rovers
An eccentricity of Land Rovers
A plod of Land Rovers
A drip tray of Landies
An apocalypse of Rovers
A smear of Rovers
A dribble of Land Rovers
A leakage of Land Rovers
A migraine of Land Rovers
A haemorrhoid of Land Rovers

We are doing well here!
 

[Wittsend]

A wallet emptying of Land Rovers 

[Richard]

A wallet emptying of Land Rovers 

Wallet? What wallet 😉
Richard

[diffwhine]

A wallet emptying of Land Rovers 

Now that one is highly appropriate - even more so if you own a current Range Rover.
