I have a few in no particular order;
1. Honda Civic Type R '08 (the latest one) - Looks pretty cool with the body kit, but not too extravogant and is quite surprising in terms of performance; 411BHP, 1051kg and 513P, not too shabby really and once set up performs nicely, and just looks the part.
2. Citroen C4 Coupe 2.0VTS '05 - Again looks pretty cool, a nice big WRC style wing at the back that looks the business and another surprising one, it looks like it'd be slow but it's far from; 406BHP, 1102kg and 529PP, again not so bad and performs well.
3. CUSCO DUNLOP SUBARU IMPREZA '03 + '08 - Looks awesome this car and performs as well as it looks, it's not got the most power, but it picks up well and surprises a lot of people at just how little power it has when it's keeping up with cars of 6-700bhp with ease; 376BHP, 1100kg and 556PP keep this thing going nicely ('08). As for the '03, looks a little more low key and is just a shame it's a standard model, a little more tail happy than the '08 due to it's FR nature, but it keeps up just as well; 394BHP, 1100kg and 563PP put it a little ahead of the '08 ('03).
4. Ford Mustang Mach 1 '71 - An astonishing car, it's got an amazing sound to it (something rare in GT5 unfortunately) and it has great performance, and has made me want the Trans Cammer which I'm considering picking up after a little more money from the Seasonal's, it can put out a lot of smoke if wanted controllably, or be as tame as a GT; 712BHP, 1309kg and 608PP put this thing among the best with ease, and looks gorgeous.
5. Ford GT LM Spec II Test Car - Looks amazing in black, it sounds the part and tears up the competition with ease, little needs saying about this as the figures speak for themselves; 801BHP, 1165kg and 686PP makes this an astonishing ride.
