Saturday I armor-alled the interior and I always do the door seals as well - both of them on all 4 doors. Put a nice coat on them - enough to coat them well. I learned that trick from one of those "'ol car dudes" - it can only help. Don't know how many older cars I've seen with worn seals. I also put leather protector on all of the seats, paying extra attention to the 'contact' areas on the corners, etc.
I also got some after-market rubber
floor mats. Found a set at Wal-Mart for $22.00 (Goodyear) that you can trim to size. This will help prolong the life of your stock
floor mats. When I traded in my Mustang for this Stinger - the
floor mats still looked brand new. They are very visible items; plus it gives two layers of protection for the actual carpet. They actually look nice in the Stinger! That kind of surprised me, but the black/grey look fits well. Can always pull them out if I want to really 'impress'
I can't post a link yet - but here's the number: Walmart # 551749090
They were cheap and seem solid - they are heavy enough so that they don't move around while getting in and out of the car.
With it being a turbo, I suspect the manual requires 100% Synthetic Oil? I haven't looked - but it won't matter - I'm only going to use 100% Synthetic anyway. Have been doing that for a while now. It costs more, but you get what you pay for.
I also plan on changing the plugs around 35K miles. Turbos will eat them faster due to the heat, etc.
And I concur with the above - investigate the proper washing techniques to avoid micro-abrasions on the paint. Typically you'll wash with one bucket and rinse with another, changing the rinse water fairly frequently. Don't cheap out and use dish detergent, it'll strip the wax. Auto soap is cheaper by the volume anyway. Lot of good videos on youTube. Don't forget to wax.. it should be good weather for it now. That'll be what I'm doing next weekend.
