Faults:
The digital dash was replaced under warranty. Although digital dashes are somewhat considered to be a non-enthusiast item, this is a jewel of a display!
The lifters have always been very noisy in this engine since it was new. The dealer replaced the entire set twice, with the last change after the warranty expired at 100000 miles at no cost to me! I am anxiously awaiting the return of my coupe after its first major rebuild at 265000, in which my mechanic noticed restriction in the oil passages in the heads' freeze plug area.
My power windows have also experienced problems with the window regulators. I replaced them myself with an aftermarket design that has worked quite well. I modified the mounting bracket on each regulator by repositioning the lower mount. Both windows operate more slowly than the originals, but the seal is great.
I have also experienced a tragedy with my power Fuba radio antenna. I destroyed the amplifier portion of the base by accident when changing a broken mast. What began as a $50.00 mast swap, turned into a $400.00 antenna replacement, as this is a special antenna with power lift and a signal amplifier.
General Comments:
This is absolutely one of the most enjoyable cars I have ever driven. It is something only Audi Coupe GT owners will understand. While there are always faster cars out on the roads, few will be as eager to play 100% of the time as this car is. It is a pure joy to drive at the limit, and every time it rains, I ask myself how Quattro can possibly be any better. This car will talk to the driver in the most reassuring language of its athletic abilities.
I never get tired driving this car, and love to recall a particular road trip, when I arrived at a road circuit racetrack after following a friend in his well driven Ferrari over rural roads for an hour and a half, only to see his sweaty, obviously exhausted face explain to me "It's a whole lot tougher to lead than follow", when he noticed I wasn't even slightly tired after keeping up with his efforts to leave me behind! This performance from a front wheel drive car leaves many to doubt its potential.
I will always drive this car, and hope that it will get the respect it deserves over time. There is a reason the 4000 Coupe GT cost more than a BMW 325 in 1988; it was and is a better car!
