: I just bought a 2009 STS4 Luxury Premium 3.6 black ice w black interior...

I recently joined the forum as a new Cadillac enthusiast!
Let me tell you about the car and ask a couple of questions.
I did a national search for an STS4 with less than 20k miles and they are really hard to find! I found a 2009 with 11,200 miles from rural Iowa, that was an estate disposition after the owner passed away. I bought from a Cadillac dealer in southwesten Illinois, closest Caddy dealer to where this lady who passed lived. The reason I know it was a lady is that the driver side handle had left hand ring scratch marks in the clearcoat and that was the only paint flaw on the car! :sneaky: Dealership included the Cadillac CPO extended warrantty to 100k miles or two years beyond the original in service date. Loaded with everything but the HUD and the V8 engine. I drove 3.5 hours there and 3.5 hours back to get the car home. I got 29 mpg on the highway.

Now the questions.
Dealership was trying to pitch me on having them do a Simonize Glasscoat ceramic paint sealer on the paint. I said no, but researched it, and it looks like that stuff works, so I bought one bottle on ebay. This product is strictly to be sold through dealers exclusively, some salesman that quit must have sold his samples and i got one bottle. I out it on and it was easy application and hasnt gotten wet since I applied, curious to see how water rolls off it. google glasscoat, pretty impressive, but not worth $600 at a dealer!

The car was originally ordered with the staggered tires on 18x8 wheels. I verified with the dealer service adviser that all the wheels are the exact same width so that when I get around to buying new tires I can go with 235/50/18's all around and do a normal rotation. Rather than keeping 255/45/18 in the rears like I have now. The dealer guy did the rotational distance and said it was onlt 1/4 inch circumferance difference so it wont affect ABS or speedometer or odometer.

Now a few mechanic questions. This is technically a 3 year old car, i am thinking brake fluid, radiator, trans are all still from factory mfg date of Aug 2008. That freaks me out. Should I have all fluids changed out in spite of it having less than 12k miles now?

I'll take some pics and post

Congratulations on your purchase. Welcome!

I wouldn't do much more than change the oil with the correct oil for now. Read your manual cover-to-cover. Set the options to your preference and drive it. Enjoy!

Chack out the Sticky thread at the top of this forum.

We're happy to help. Let us know your experiences.
