I've driven the 4.0 Chimera & have to say I wasn't that impressed. The JE engineering 3.9 litre V8 TR8 I drove previous to the TVR was far more impressive in a straight line. I pulled out behind an Evo 6 coming up the A9 & he was visibly shocked to see an old car staying with him all the way.
However, to get back on track (ahem) I'd love a Speed Six Cerbera
TVR's are fast however the build quality is poor. I live 5mins away from the factory (well old one now) and i work with 3 lads that worked there and they told me some storied of what went on there. Some of it is harsh.
