I have been lucky to have both a Tuscan S Mk 1 and a Cerbera lightweight 4.5 for 9 months and 1 1/2 years respetectly and all in all it was painfree ownership
The tuscan s was always trying to bite and hence i drove it with loads of respect and i guess i would have been slower in it than a zed but the cerbera was just everything and more. it never broke down and i only needed four mods to be happy: nitron colies, front under lip spoiler and sports exhaust and swapped for anthracite wheels
I had a few trackdays with it and in the dry in comparison it will eat the zed alive. i swapped ends thrice in the wet...and gave her more respect then.
I think since then every car i have owned i have tried to make it more cerbera like in terms of outright handling, noise and power and one of the reason i enjoy my zed so much is the fact that its the closest i have come to achieving this
I have driven the sagaris and the tuscan s Mk2 and they are both better than the cerebera but i will have them as second cars if money was no object because at the end of the day TVR ownership can be hell and i was just lucky
