That first 450, the seller needs to be told he's dreaming. And there is no way that drivers seat is 123,000, nor the wear on the drivers door card. I think 423,000 sounds more likely! The whole 'genuine reason for sale' statement always makes me suspicious as well.
The green car is a better car, although still expensive given mileage. And its an SEL, without a towbar, so the transmission is less likely to be stuffed.
The gold SLC is almost certainly an import with a replacement speedo, so that mileage is unlikely to be correct. Presumably it had rust repairs at the lower part of the body and they used a different colour to fill it. I wonder if its had an interior change as blue velour is an odd combination with Ikoen gold.
The Green SL looks the pick of the bunch in my view.
The last one is a $2500 car at best. the paint is ruined.
