The Bonneville SSEI was a much better car and developed into a very good car. I still never felt it was a true Pontiac as it was just so cooperate in the mechanical bits.
It was the most interesting of all the GM brands on the same platform.
Here is the deal with the German cars. While they can build some exciting cars, some can still be money pits.
But to be fair. Here is the deal. I had several customers with Benz in the 80's and I have to say the only real issues we saw were tires, brakes and one Exhaust in 300,000 miles. on a 300 Diesel. The Cosworth sedan we never saw an issue in 100,000 miles.
On the other hand I saw money pits on multiple BMW models.
The Benz parts were not cheap but it needed so few parts it really did not matter. I am sure with complexity the cars today are more difficult and expensive to repair but that was not always the case. Like my father said when he lived in Germany they used Benz for taxi's because they reliable and did not break often.
As for Pontiac I like many long time Pontiac fans did not miss them when they died. After so many years of GM just miss managing it we feel it was a mercy killing.
