HLBS is a miniature manufacturer primarily catering to the wargamer, but toward that end they have a range of light vehicles for the British army in 1/48th scale (they also have a BRDM-2 and a Stingray, but no images of those are on their website).

Anyway, here's the page with the British armour:

These are for wargaming, but are actually rather nice, some better than others (the SAS Landrover is pretty impressive for a wargaming piece). In any event all could, at the very least, make a good start for a superdetailing/correction project.

By the way, here's the index for the entire range, which is primarily infantrymen (elites of the West plus Taliban and African guerilla types):
