We know that Jay Leno, who is now retired form TV!, is in the UK to promote the new Jag Xj. We also know that Top Gear 13 has already featured guys like Michael Schumacher and Ken BLock, so when Jalopnik runs a report saying that Jay Leno has been spotted filming on Top Gear base as the star in a reasonably priced car, it must be true! Oh, sorry if we spoiled it!
