My interior is different than the one you are talking about so I can't help you there. But as far as the Big $$ oil changes go, I negotiated 5 free of those bad boys into my purchase, which at 10K mile intervals will bring me to 50K miles. Then I got another 5 or 10 included with the extended warranty. With other cars I've purchased, I never bought the extended warranty. But for this baby, yeah - you'd better believe I got one. Try having at least 3-5 oil changes included with your purchase.
