Dated poorly built and by current standards not that quick either.

Couldn't you say the same thing about the (300bhp) 1962 Ferrari 250GTO which sold at auction last year for $48.4 million?.

Sure they can be tuned if desired for 400bhp plus but certainly not going to last very long with that output....

My understanding is that the racing versions could produce 550bhp reliably.

Everyone differs but that kind of vehicle just does not warrant that kind of money.

Horses for courses. A car is worth what folk are willing to pay for it, i.e, this car is worth the price it fetched.

I consider myself a petrolhead and, imo, the aforementioned Ferrari is in a completely different league to a Sierra Cosworth. But take my mate Ben (who would consider himself a car fan), if he won the lottery, he would have no interest in buying a classic Ferrari or any other fragile Italian supercar. What he would do, is buy absolutely the best Sierra Cosworth he could find. Why?, because that is the car he lusted after as a youth.

Not good build quality Sierra's of that era or in fact any era come to that. Back in the day some of them were showing bits of rust at 4 to 5 years of age. Before paying that price would have made sense to put a mini camera inside the vulnerable areas of the inner bodywork. Everyone differs but that kind of vehicle just does not warrant that kind of money. Dated poorly built and by current standards not that quick either. Sure they can be tuned if desired for 400bhp plus but certainly not going to last very long with that output....

Expect it's been bought as a bit of an investment so they won't be worrying about that.
