Guessing this is a v8? If it is I don't see the "upgrade" as the performance between this and the m3 is non-existent or neglible. Now if it was for simply looks than I totally get it. Or if its a V-10 than forget I said anything!
Also why would he need another daily driver? I don't get those comments as why would you not drive an R8 daily?
If I had a Zonda or something crazy than sure but even a ferrari I would daily drive. Why not?
