Difference is the Phaeton has better quality along with it being twice the cost.
Another factor is you must be a AARP member to drive any Buick.
There's too many other cars in that class I would buy before buying a $75K Phaeton.
Edmunds.com review.
Pros
Powerful engine lineup, superb interior craftsmanship, standard all-wheel drive, more passenger room and simpler interior controls than competitors.
Cons
Excessive weight impedes handling, poor fuel economy, premium price for a non-premium brand.
There's no doubt that the Phaeton is a full-size luxury sedan of the highest caliber. Like every other premium luxo-cruiser on the market, it delivers heaping amounts of power, faultless construction and enough luxury amenities to keep four passengers content even on the longest of trips. There's a reason it costs as much as it does, and those with the means to buy it aren't likely to be disappointed.
But the question remains: Why buy the Phaeton and its Volkswagen baggage when you could get one of its equally competent and more prestigious rivals for roughly the same price? Rational reasons are few and far between. The Phaeton doesn't offer anything that the others don't and its slightly lower price has little relevance for this class of car. Since its launch in the fall of 2003, the Phaeton has by all accounts been a sales flop. Then there's the question of its future. In the likely event that Volkswagen decides not to build a second-generation Phaeton, owners of this car will be left holding the keys to a very expensive experiment. If that's a risk you're willing to take, the Phaeton will most likely reward you with many years of faithful service. If it's not, buy one of its equally qualified rivals instead.
