while the F40 was an awesome car, as was the XJ220, they were both still compromised. the F40 was near impossible to drive on the edge, the interior was straight out of a race car, and it wasn't ideal for anything related to daily driving. thats why they had the TR and the 456GT and the 456GT. The XJ220 was compromised form the start when they didnt get the V-12 they wanted. and then, even after it broke the record for fastest production car, they couldnt sell it. wasnt there still a new one for sale in london until last year?
what the 599 does is make a car with performance on par with the F40, but they do it in a car that is more comfortable, better ergonomics, higher quality workmanship, and significantly more reliable. and not just that, but i have never found the F40 to be an attractive car. i think its beauty is in its functionality, but its not pretty. the 599 at least makes an attempt, and its functional. and they sell too. a lot of them. i bet that they will sell every 599 they make, and probably have a demand on their final model year.
