I looked at an Auralis rs2000 when i was looking for one, it too had a white engine bay, its just the base coat, they didnt bother painting the engine bay to save money. Dark colours, the bays are usually matt black as Al says.
My red one like less's has a non shiney matt finish red in the bay.

Is it 2wd or 4wd? either way its pretty rare in that colour, look after it if you get it
Check for rust under the spoiler where it meets the boot as they all seem to go here but can go unnoticed. Arches/ under front door rubbers, all usual places. Hope its a good one.
