This vehicle (an '06) has been very reliable and versatile. It handles great, looks great, and hauls the mail when you want it to. MPG is about 30 on the highway. Cargo space with the back seat down is amazing. It did have more highway cabin noise than I would have liked during the first few years. A switch to Continental Pro Contact tires along with precision alignment took care of that. This car needs precise alignment, not just "within specs." I highly recommend this one.
Had A3 2.0T 6MT Sports package. Very fun to drive, but very unreliable. Over 4 and 1/2 years of owing it at 45000 miles, I had window sensor issues, hutch lock system replaced, ignition coil failed 3 times, cannot keep alignment more than 6 months, coolant start leaking, center console for rear broke off, temperature sensor failed. Dealer in MA will charge each inspection $110 even it is nothing more than error code download and same task. Start costing me a lot to own it. I finally got rid of it
Seat. 6MT. Turbo. Storage space.
Reliability. I don't understand why there are so many problems when technologies are shared with so many different models from Audi and VW.
It seems that Germans have not discovered aluminum. All the interior design is in plastic with silly parts that break and are not covered by the warranty. Of course, the crooks from the dealer will charge $1000 for any stupid part and make you wait for a week to get it. I used the back seat arm rest once and it broke; I plugged an ipod in the cigarette lighter and it broke; the two moon light roof hatches broke; the bolt that holds the spare tire broke, etc. In addition, the car gets a check engine light every six months. As another reviewer noted, I had to change the Pirelli tires at 10k miles because they were really noisy. Finally, the dealers are pretty bad (but that's another post)
Handling; acceleration with the turbo on
Get new dealers, run some quality checks on the car
... and just passed 65,000 miles. Still love driving the car. Clutch still good. So far, failures are: a/c compressor, turbo valve, psgr lock button and radiator gave way at 52,000 miles; the last one really got me bent 'cause the car was just out of warranty. Now have check engine light on, but car is running fine. Coded as fuel cap leak, so not worried. Car is on third set of tires. Original pirellis VERY noisy when worn, got zeons then yokahamas. Zeons good but wore out in about 5 minutes, yokahamas are a good compromise.
Engine, handling, BRAKES, looks, gearbox, overall performance, comfort (in front), utility of hatchback design.
Fuel economy, spotty reliability, wheel hop, comfort (in back).
I've had an Audi A3 2006 and it's been nothing but trouble, with numerous repair visits to the dealer (covered by warranty until recently). The problem areas have been the fuel injection system and various electronic components. Just in the last 6 months, I've been to the dealer 7 times. If you like to spend time in the waiting room of your dealership, this is the car for you. Otherwise, there are much better (and cheaper) choices out there.
