I think the owner has some "personal" issues..
1. You buy yourself a lamborghini.
We're all impressed. Admiration received from all petrol heads and even people who don't know anything about cars (it looks fast, and everyone has heard of lamborghini)
2. You get your lamborghini turbocharged. Twice.
Not satisfied with the attention you get with your 'stock' lambo, you seek to impress even more by blowing a bunch of cash on a twin turbo conversion.
Petrol heads were impressed already. Some may be, er... more impressed but pretty much you had us all at point 1. Folks who don't know about cars were already impressed at point 1 too.
3. Not satisfied with the attention the twin turbo lamborghini is generating you decide to put some biiiig garish stickers on the side to TELL people that you've thrown a bunch of money into an already fast car. Helpfully, you explain what VTTT actually means, so we don't think that your sticker guy had a stutter..
Its at this point that the petrol heads start to think.. "actually i quite liked it before he messed with it". Folks who don't know about cars probably are a little beamused as they probably think that all wedge shaped cars must have at least a dozen super-turbo-chargers already..
Only joking..
