250 testarossa or 196s dino video???

[carse]

hi, i remember seeing 2 different videos of what is either a 250 tr or a 196s dino. the videos where of it goin down a country lane one from on board and one from outside where it could be heard on the overrun as the driver lifted off. sounded absolutely gorgous so im wondering if anybody could point me in the right direction as to where it is on the web!

many thanks
