I can't answer your question about knowing who owned them, but my personal opinion would be to stay clear of the first one, I see its a cat C, I think it looks like its had a front end collision and has been repaired on the cheap.
The front bumper is not an edition 30 one.
The headlights look well past it, yes I know you can wetsand them but you get what I mean.
The alloys look to be off a gtd?
Missing centre caps
Rear wiper, are they trying to make it look like a delete or can't be bothered to get that piece.
On the positives the interior doesn't look in a bad state, but there is no way id part some of my money on that.
I like the other two you've put up links to, out of them i'd go for the first grey one you put up, looks in really good condition and the low mileage appeals to me.
The xenons of the second one immediately grab your attention and does look in nice condition, if you look closer in the picture of the rear left alloy, you will see the whitework coming through and slight curbing, the caliper doesn't match and if you look where the rear bumper meets the rear quarter they don't line up correctly, I know they're just little things and its a10 year old car but you want the best you can get.
Good luck to whatever you pick!
