The basic model in the Woodway line. When your base model is $7k you know you are looking at a different animal. If you get a bearing problem in this machine it will be similar to a giraffe getting a sore throat.
$7000 is a bunch to pay for a machine. You can expect that this treadmill won't require replacement in a few years and if you like the 'set it and forget it' commercials and have a big pocketbook, this treadmill may make sense for you.
