If the picture is accurate, the 25,000 miles is possible. That front seat looks almost perfect, and the carpet in the driver's foot well is damned nice too. To me, though, it looks like it is missing side trim. Having just the rocker molding looks more like the Bel Air trim than Impala, or was the side molding an option on Impalas. I thought it was standard equipment, in which case it is missing.
Nice wagon BUT look at the rear kick panels. They are discolored, so at some point the car sat outside alot. Nice wagon, but for $10,500 the interior should be perfect. I love the 74's but this is a nice car, not a great car. Anyway, makes mine look even more like a $8,500 wagon.
I blew up the side pic. Seems to have an 'Impala' emblem on the fender. Interior looks to be 'Impala' level as well.
