My 2000 Impalla head gasket was leaking coolant into the engine.
went to the dealer, total cost of repair was $1030.00

was thinking of a new Impalla 2006, but now not so sure about purchase.

It's unusual for a head gasket to be leaking. I assume it is some sort of V-6 engine?

2006 Impala's don't have the same engines as your Impala. The new ones are a 3.5 V6, 3.9 V6 and the SS has a 5.3 V8 with 300 + horsepower.Good Luck

Are you sure it wasn't an intake manifold gasket? GM 3.4 l V-6 engines are notorious for intake manifold gasket leaks causing coolant in the oil problems.

unusual?
more than half of the impala drivers I know got their head gaskets replaced. maybe unusual just for me.
That is really, really unusual. Rarely does a head gasket go bad on the
2.8-3.4 series or the 3.3-3.8. I would tend to disbelieve until backed up with test data: compression check, leakdown test, exhaust gases in the coolant, etc.I think you probably mean: "the intake manifold gasket was leaking coolant into the crankcase"?

Completely redesigned the intake sealing surface and gaskets with the introduction of the 3.5L engine. Too early to tell if it is finally fixed. Hopefully it is for GM's sake.
You can ask, but it isn't likely that they will pay. As for the dex-cool, it's more a design/engineering problem with the manifold and gasket than a coolant problem.
This problem is over a decade old now and GM has tried many "fixes". Will the 3.5l engine have the problem? Only time will tell.

If the Dexcool is contributing to the degrading the gaskets, why is GM still using Dexcool? Their competitors seem to be doing fine with the green stuff. What is the value add, I guess is the question?
The story that DexCool is at fault is largely an urban legend. There IS a problem, but it may not be DexCool
I see. Are there other advantages to DexCool? If so, I wonder why everyone isn't using it in their new cars.
You haven't been paying attention. The Asians have been using coolant similar to Dexcool's OAT for quite some time, Ford and Chrysler are using a hybrid version of the Dexcool OAT inhibitor package also.
The big controversy seems to be about the use of the plasticizer 2-EHA as one of the components of Dexcool. A plasticizer softens plastics and apparently can do so with some of the seal materials in vehicles.
None of the other OAT or HOAT type coolants use 2-EHA, it is unique to Dexcool.
