I own the Escape outright. The dealership is near my work. The bulk of the rust was hidden inside the sub-frame and the mounts for it. They found a used sub-frame and wanted $500 for it + $2,500 for the work. That's $3K for a vehicle that I paid $3.25K for. The rust wasn't just at the sub-frame though and I wouldn't have felt safe driving it much longer. This is what happens when lazy people drive in snow on salted roads and never wash the snow and salt from under their vehicles.
This car has no rust in any important areas. Gets MUCH better gas mileage (I drive 53 miles round trip a day for work) and has even less mileage than the Escape.
Yes, I have already ordered the DD dash kit and wire harness for the radio. I will be pulling all my stuff out of the Escape Friday. My sound deadening was going to go in the Escape when it gets warmer outside so now I will just do the doors on the Elantra instead.
