"It took some time to select just the right shopping complex, off just the right highway and just the right distance from Seoul, to house a 59,000-square-meter store. (•••) In all, it took about 6 years for Ikea to unveil its inarguaral store."
- In the above sentence, I think the part between commas (, off ~ Seoul,) is there as the supplement to 'the (right) shopping complex' and that the 'off' is a preposition because of the location of two commas=(,off ~ Seoul,). Also I guess the 'off' is omitted after 'and', i.e., 'and (off) just the right distance ~'. Am I right or wrong...?-?
+and if that's the case, does the preposition 'off' mean 'near to'? (not away from)
