TVR, hmmmm. Like Alfa Romeo, I sort of understand why they have a cult following, but in reality, most of the cars they built were fairly rubbish.
Generally they look good (Cerbera and Sagaris are the highlights) and they are all decently quick in a straight line, but they all suffered from terrible build quality, horrendous reliability, non-existent electrics and rubbish handling.
The Speed 6 engine (as fitted in the Tuscan, making 440 hp in top spec 4.2l guise) has an awful reputation. Yes, it makes decent power (though nowhere near as much as TVR claimed for it - EVO struggled to top 170mph in one), and a decent noise, but they are a horrendously unreliable power plant. It was unusual for one not to need a full rebuild inside 25k miles, and even the best ones struggle to reach 35k. Some owners had multiple rebuilds under warranty, with some lasting less than 10k.
Given how unreliable the stock engine is, I'd have serious reservations about the Typhoon... 1) I call 'custard' on the claimed power output, and 2) it will go bang whatever power it makes.
Meh.
