(Depending on what it is..) getting a second car and driving it for a while really makes you respect and fall in love with your RS6 all over again.
I needed something to take some of the miles off the RS6, and bought a new Mustang GT California Special (black on black) last week. I wanted something totally different, not to mention Ford is basically giving cars away (5k under sticker, 0% financing for 72 months, 0$ down, 3 year service package).
The car is not "slow" by average standards.. First day i had the car i did a Kenny Belle supercharger kit, exhaust, pullies, coilovers, headers and tune. Sounds menacing, and fun to drive.. maybe 515hp-520hp
But after driving the new one for 5 days.. i took the RS6 to work today. My God that car is faaast. Really fast. I was totally jaded after driving just the RS6 for over a year. I know Mustangs aren't even in the same league as the RS6, so no need to remind me, but even still - after driving what could be considered a quick car to average people, the RS6 sent me into euphoria all over again. Sometimes you don't realize what you have until you loose it.. (or leave it in the garage for a week)
