: Sts '05/'06/'07?

Gents, I'm struggling here finding anything with a search so I'm deferring to the experts. Let's say equivalent mileage and condition on a non-V STS. Are there things to watch out for on the '05 model?

Did Cadillac make any upgrades on the '06 and '07 models that would warrant holding out for one of those years? I can rattle off 20 differences between an '82 and '83 Eldo, but the Sigma series STS has me stumped...? :yup:

The '07 V8 uses a 6-speed auto versus 5 in the previous years. Of course, the '08 has the nice DI V6.

The new series 05 & 06 STS had a lotta bugs and most were worked out in the 07. The major difference is the 6 sp trans. Gotta keep up with the imports ya know.

Except for the Bluetooth connection issue, my 2007 STS4 has been a stellar ride. Even with the V6 engine (23.8 mpg ave)

I don't think so....

List some examples of all the "bugs" that were addressed ;)

Anyway, with these cars depreciating the way they do, why would you buy-in to the major portion of it?

With "equivalent mileage and condition" save the most you can, (like 40k), and get an '05!

I have an '05. There weren't many bugs specific to that model that I know of at least that weren't carried over in '06 and '07. Most all had the rear differential pinion seal recall, but actually my '05 was not included. There was a software update on the nav equipped vehicles that is available to anyone that takes their car to the dealer. GM didn't improve hardly anything on the car over those three years that I know of except they went from a five speed to a six speed transmission as mentioned above, but the five speed is an excellent transmission.

Thanks for the feedback guys- looks like we've got a low mileage '05 headed this way!
