I have tons of Top Gear and CAR magazine and all I can say is that these are by no means the best motoring mags in the uk, at least not for me .. i dont know if you have heard of EVO magazine (formerly known as Performance Car)
this mag focuses only on performance cars and the writing and photography are truly exquisite. every issue has a handful of simply awesome cars and the car of the year issues (december/jan.. cant remember) are sublime.. i just bought this months issue of CAR magzine, where they had their performance car of the year, and compared to EVO magazine'sI found it dull and uninformative...
i dont know if you ll be able to find EVO in the states but its a very fast growing mag so they might well export it....
