I'd go for the Audi over the Volvo. I have a S60 T5 and used to have an A6 3.0 TDi.
If you decide to get the S60, get the T5 AWD or the T6. Stay away from the 2.0 4-cylinder T5.
The engine is great; the issue is the Ford-derived Powershift transmission.
Ford had some class action lawsuits...
I don’t know where I got it. Apart from the Airport, Flight and Gautrain, I only had contact with about 10 people. This includes 4 Uber Drivers and colleagues.
