135,000 on the 3.8 Litre Series II V-6 is nothing. The 3.8 V-6 was one of the best engines ever. The V-6 did have problems with the plastic plenum gaskets M. They would leak coolant, and have to be replaced. Also, the transmission was the same one that was used in the 2000 through 2005 Chevy Impala, and that became a real problem in 70,000 miles of driving. The transmissions had to be replaced.
Yup it's was a 2005 Buick Park Ave ultra special edition I have one my self only like 3k of them was made they also made some with a vinyl top I have a short video of it on my channel
Also, doesnt the limited have climate control and sound concert 2 has the base for the trim? It doesn't have neither Edit: just the upgraded speakers. It has climate control 😂
