BMW love, hate 
2006 BMW 3 Series Convertible 330Ci 2dr Convertible (3.0L 6cyl 6M)
Ditch run flats, then a great car
 I dreamed of owning a BMW for years.  I finally bought a used one with 11,000 miles on it last year.  What a disappointment. The road noise was horrible and the ride rough.  I actually tried to take it back but couldn't.  About 3 months ago, my wife got a flat tire and I decided to replace all four tire with regular tires.  What a difference.  We both love the car now.  Ride is quiet and smooth.  Totally different car.  I bought a new rim and had one of the old run flats put on it and keep it in the trunk as a spare.  I also bought a compact jack.  Sure it takes up a lot of room and adds weight, but that's a small price to pay for totally changing this car from one I hate to one I love!
