You sound like you're in the same position as me mate, except i'm not quite ready to buy just yet.
Difficult to come by aren't they? I'm not quite as strict as you regarding mileage though it has to be under 100k. And i'm only ruling out a silver one as i've owned 3 silver cars and feel like a change.
Not sure if I can answer your question but i've been looking for a while and i've never seen a solid bright red.
Report back on how your test drive went, if you don't mind. I've driven a couple but they have all been heavily modded ones and they were saloons.
