2005 Buick LeSabre Custom 4dr Sedan (3.8L 6cyl 4A)
I've never been more pleased with a care in my entire life. Very smooth ride, incredibly comfortable interior, and quiet as a mouse. The mileage is phenomenal given the size of the car. I commute 60+ miles each day so really appreciate how comfortable the interior is. The suspension soaks up the potholes with just a soft "thump, thump".
XM Satellite radio w/steering wheel mounted controls. Well worth the $13/mo subscription.
Start making them again...why mess with success? The rear seat is pretty tight for even slightly taller than average folks. The radio just looks dowdy and a little cheap compared to the rest of the car. That's a typical complaint of GM cars though I think.
