I have had the intake gasket replaced once, the oil pan gasket replaced twice and now both heads are leaking and the intake is leaking again too. I have had to have the seal around the back window replaced and not the front end feels like it is coming apart. I really like the ride you get with the impala, but that is about it I guess. I will not buy another and this is my second one... I guess I did not have the first one long enough to find out.
