Not that this will make you guys feel better, but 2 of our 5 Subaru's we have/had had there engines replaced for oil consumption under warranty. One is still burning oil with the new replacement engine, not as bad though. The others don't burn a drop.
And BTW I heard same issues with Audi's...
You know, I never even looked at a Prius until 6 month ago, my Audi S4 was coming to the end of the lease, and I got a new job job and now have to commute 25 miles with bad traffic...I was seriously considering buying the Audi off the lease, but then decided to buy the legendary Coyote Mustang :).
I know, it's like being Dr Heckyl and Mr Hype...lol... opposite ends. You're right, the Prius is a Long Island thing, I use it as a commuter car on the HOV lane...
There is a sound insulation trunk mat made by a member here called TKO, you can try that , I bought it and believe it helped a little, my wife has sensitive ears, and suffers from the drone as well.
I think a closer comparison to the Stinger GT would be the Audi S5 sportback.
Regardless these cars are faster than the mustang GT's 0 to 60, mine with simple stage 2, tune and one pulley, was easily running at 3.5 seconds. It is due to the superior 4wd system they have. To quarter mile is...
On a more technical note of this discussion, I never drove a GT350, but my father's neighbor has one, and says he does not like the way it drives due to the luck of Low end torque. He has it sitting as a future collector car.
The low end torque is a problem for Street driving, the voodoo engine...
