No body on TVR? Which platform? It's fine here.
The Cadillac is pretty awesome. Very enjoyable to drive and not too slow in stock form either, though it's just begging for a drop.
The TVR... I doubt this car will weigh just 1200 kg, let alone perform as good as it does. TVR is a brand shrouded in Easter Bunny myths and worship from sources that take pride in sounding alternative for the sake of being different only. The car in the game is an example: no colors other than red, no Cosworth badging on the engine, nor even Ford (you'd expect the brand to promote these), six buttons on the sides of the steering wheel that look as if taken from a random Asian ricemobile, and overall bland design (the Sagaris and the Tuscan are more attractive). A nod to them for naming "Griffith" a car powered by a Ford V8 sourced from a Mustang like the first Griffith 400, which was a Grantura with a 289 swap, but it's simply very difficult to take this car seriously at all. The 992 is proven at least.
As if it wasn't enough, the Griffith should have been grouped in the "Modern Supercars" category, yet it was put in "Modern Sports Cars" when it sits well above peak A class, and far above every other car in its category in stock form. Excellent advertising, bad for gameplay, since it can't be used in A800 anyway, and S1900 requires more extreme mods.
