Mugen Civic RR - I'm surprised it beat the S2000, maybe they should've used the S2000CR for a more even match. But still for me, rwd > fwd.
Road tax thing - I can see it being relavent to UK viewers, but I skipped it.
BMW X6 - that thing is hideous, if they can make the X6 handle that well, why not drop that AWD system in the X5? It'll be more practical, better looking and seats 7.
Tesla and Beira - The lack of engine noise of the Tesla just feels weird, for the same money I'd much rather get the Exige instead. THe Beira is just a freaking Saturn Sky with a LS2. Does the EU market get the Sky Redline with the turbo engine? Just get that if it's offered.
X-Bow - I don't like the way this car looks, and I agree with Tom, just get the Aerio Atom instead.
Overall, not a bad ep, 7/10.
