I always drive the last couple of hundred yards reasonably sedately and let the car idle for about 30 seconds when I've parked up. I think it sensible to take that approach on all turbo cars. It's not actually a hassle - just get into the routine and do all the stuff you would've done after turning the car off before you turn it off. Also when starting up, do not sit there revving the car to warm it up. Drive straight off don't rag the proverbial out of it until it's warmed up. I've heard a ragged turbo (and it doesn't sound pretty) on a car I looked at to buy. Basically, the guy fired up the car in the morning and top revved it up a steep drive onto a steep hill and then first geared about 50 yards to the junction. He showed me a receipt for a brand new turbo within the last 6 months. The car sounded like a helicopter taking off. So, if a turbo can sound that bad through improper fire up and turn off procedures within six months, think on - 30 seconds :) Paul
