Owner of 2016 bought in April of 2016.
1. Has any one considered pin striping or other sporty changes?
No. The car is beautiful as is. I still get positive comments on it from passers by.
2. Any one had trouble with getting oil filter in car? Bought 2016 that had been sitting on lot for a year and at 1000 miles computer called for oil change and local Valvoline oil change shop had hard time.
My first two oil changes came free with the car. The Buick dealer had no trouble finding and replacing the oil filter. I will take it back to them for all of the oil changes and similar repairs.
3. Have one part of soft top that does not close properly. Anyone else?
No. I would take it back to the dealer. It is still under warranty. I am able to take mine through the automatic car wash without any leaks.
4.Anyone having hard time using dash controls easily. Seem to have too many buttons.
At first it can be confusing but after awhile you get to know where the important ones are and then they can be found and used without taking your eyes off of the road.
All in all after a year I am still very happy with the car. It is comfortable, fun to drive and gives me a great tan in the summer (I store it during the Michigan winters). I am very impressed with the fact that I can drive on the freeway with the top down and the windows up and hold a conversation with the passenger or hear the radio. No other convertible I have owned has such a quiet ride with the top down.
