I regret so much turning down a free upgrade to a Q7 a while back because I thought it would be a gas guzzler for a long road trip and took a X3. I found out afterwards the Q7 is also a 2L turbo. Is that enough to power such a large suv when you drove it? The A3,A4,A5 are also the 2.0L turbo.
I rented the a5 once — probably the smoothest car I have ever driven
