Ian, the fact that you haven't bought it already speaks volumes.
When I bought both of my Zed's and my Gallardo, I nearly passed out when I saw them. My heart beat was racing, sweaty palms, voice wavering, legs felt weak and I couldn't hear anything the saleman was saying to me. I had to have them, at almost any cost. It's emotions like those that developed into a complete obsession with all three cars.
From what your saying, you don't feel like that about this car, which means it'll be up for sale before the end of the year once you've realised your mistake.
If the car doesn't grab you from the off, it's not for you. Save your hard earned for The One
