I traded my Superb and got £3k px on her, she went to a trader who had her listed at £3995, and now it's gone to another trader and is £4450, so who says Superb's devalue like a stone, and whoever buy's her in the end will be getting one good car if she continues to perform as she did when I owned it.

One heck of a lot of motor for ~£4k. That's why I have deecided to just pile up the miles on my existing Superb rather than sell it. I'd have to spend £20k at least, plus my car, for a new one that is really not significantly better. I'm keeping my £20k in the bank for now.
