I'll have to look out for that episode, though they have them all online for viewing. Hammond is the only one on the show that appreciates Porsche for what it is. I recall Clarkson choosing the M "Zed 4" over a Boxster S on a prior episode...all engine with an inferior chassis.
Not true. Captain slow said he has a Boxster S for 4 years (mentioned in the same episode when he reviewed the Spyder) and he also has an aircooled 911 (video on top gear website).
