Overall I like the styles, though they need to work on interior design. Here again, the TT designers did great on interior, A4 less so but ok. Audi brand reputation and image to me is one of style plus excellent handling. see full Audi A4 / S4 / RS4 review

This car was taken to the dealership during the initial free maint period of 50,000 miles. I always provided my own synthetic oil as the dealership wouldn't use synthetic if they provided the oil. After 50K, I did attempt to use the dealership on a couple of occasions only to be shocked at the high dollar quotes for the most simple of repairs. They wanted $900 to replace the cam shaft seals. $1800 for timing belt kit install. The dealer attitude is that owner repairs are only done by fools at their own peril. My experience with this car has led me to understand that Audi vehicles do require more maintenance and attention than your average Japanese brands. It is a German car and there are engineering qualities that I admire. But it ain't a spaceship requiring a highly skilled scientist to work on it. Given this snooty attitude I experienced at the dealeship, I wish Audi (Service Reps) would be less about making a buck and more about pleasing the customer. Audi cars are fine vehicles. However, if you want to own one, try to do some of your own maint and repairs. I see too many negative comments in other review forums related to the high cost of ownership due to repairs at dealerships. I understand that some folks can't or won't work on their own vehicles. If this is your situation, I would not recommend an Audi. see full Audi A4 / S4 / RS4 review
 

TrueDelta Reviews the Brand Reputation of the Mercedes-Benz C-Class

Mercedes-Benz C-Class Brand Reputation: Pros
YearComment
2015 Mercedes-Benz has been walking a tightrope. On the one hand, many people who thought nothing of buying an Audi or BMW couldn't quite see themselves in something so lofty as a Mercedes. On the other, attempts to counter such perceptions risked damaging the brand's equity. Despite some missteps over the past two decades, Mercedes-Benz has managed to avoid both Scylla and Carybdis. More people than ever perceive a Mercedes as a car they could own. Yet it retains more prestige among the general population than Audi and BMW. see full Mercedes-Benz C-Class review
