Here in PA, we have to take our test in a car owned by someone, so I borrowed my girlfriend's Porsche.
There was a great deal of amusement watching a 36 year old guy take his driving test in a Porsche, by the teenagers taking their test.
Parallel park was remarkably easy since the spaces they provide are big enough for a SUV. The Boxster is a great car to park!
However, the random misfiring problems I'm having right now were problematic because it means you have to rev the engine a little to get going! The instructor said "it's not the autobahn, you know!"
The other problem is forward-visibility which means you want to stop a bit closer to the stop sign than they're comfortable with, so you can see to go around the corner.
The instructor kindly passed me, despite a few cultural mistakes. And asked me to "park his car up in the parking lot when I was finished"
Anyhow, thought I'd share my experience. Anyone else take their test in their Porsche?
