I ordered my rear seat covers at Fall Carlisle. I believe it was 20% off at the show. The lead time for colors is 7 months, so to save shipping, I just spec'ed a Chrysler Carlisle pickup in July.
You might also check with Dante's. I got a better deal through them........and a bit sooner than what Legendary quoted me. It still took about 9 months to get. I just made a carpet order a couple of days ago with OC Carpet. They carry the ACC carpet kits and have a 50% off sale currently. According to them, it should be shipped to me next week straight from the manufacturer.
They always do a thanksgiving sale or close to it month 11. I bought all my interior and install items then!
There can be better sources for carpet and more at Profit or others. IE Legendary did not offer my Headliner on their site but Profit had it and was perfect! Made by Legendary!
Seat upholstery is best from Legendary! Foam? you might want to check Pgclassic!
