Off topic, but talking of multi-story car-parks being fun, you can't beat the sound of a V8 on the Channel Tunnel Shuttle if you are first to be boarded. All 24 carriages. An 800 meter reverberating aluminum 'tube' (attacked at a sedately 5 mph of course!). That's with a Rover 75 V8 deep 'burble'; guess a 260 with Zero's would be something else again.
