I'd like to see them do sth in Norway. Great landscape with fjords, i guess they could make really nice views on the cars with those.
Maybe they could go to a winter testtrack there... Other possibility: Japan... far abroad but quiete interessting landscape though and there a tons of japanese cars to feature.
Loving the ring race idea, and japan, and ZR1. Definitely needs to be a GT-R vs 911 review. Scuderia needs to be tested. SSC said they were giving an Ultimate Aero to top gear for testing, so maybe it will show up in season 11. Only do really big name stars in SIARPC and shorten it. Longer and funnier news segments, keep the 10 episode format. More cheap car challenges, more cars need to be tested for the power board, and get the stig more involved in the films. +Mrs. Stig and the Stiglets.
