We own 4 Buicks of different years which have all turned out to be extremely reliable.
our 2007 Ruby red Rendezvous has 108 cu feet of cargo space .. more than any CUV it's size... and gets a easy 25mpg even going up and down the hilly highways of PA.. I change my own brakes and the Lucas all alloy brakes are very easy to change rotors and pads... never had a bolt stick because the alloy does not rust. The ride is very comfortable and quiet.
Take care of this car and it will take care of you. At 4,000lbs it will be safer than the tiny SUVs I see running around with more interior space and the option to take out the rear seats. Very good practical vehicle.
Seats that come out if cargo room is needed. Gas MPG is very good for a vehicle of it's size. Very good Lucas brakes. No rust brakes ... body panels and tailgate.. not even thinking about rusting after 6 years.. and even my 2002 Rendezvous with 108K miles has no rust after 11yrs! The powerful V6 engine is very quiet and smooth.
The horn button.. you have to push in the right spot to beep the horn which sometimes you don't want to look for. Hard to think of improvements.. very well thought out and built vehicle.
