I had to fly from Florida to Wisconsin to purchase my car, and drive it back down, so u are 1 step ahead.Factory Mr-2's are a rarity, and u are lucky to have one... modify it to your likings, not someone elses. Seats are fairly affordable no matter what u do. If they are leather, I would reupholster them. If they are fabric, I would ditch em, or put leather on em. Especially if u have the lumbar support, and inclining or declining legrest. Otherwise like these other guys said (EBAY). The seals are waaaay expensive, and it all depends on what u need.... there are a couple of cheap and easy ways to get out of it.,.. if u are lucky. But the seals are actually the entire door I believe, so thats why they are so expensive. This has been a topic many times b4, and u can look it up by doing a search on TN. I would also recommend that u become aquainted at mr2oc.com as they are like a brother site to here. And they have a huge selling section. But for answers, I like this place and website better.
Cheere m8, and have great fun with the new car.
