Well they are coupes, so they are likely to resemble other coupes in some way or another.
I know it's cool to have an opinion which differs from that of the popular press, but the Maserati looks dated, and won't age well. I too prefer the V8 Vantage to the DB9, the proportions are nicer, but the DB9 is a great looking, elegant, sleek, well detailed car. It's just a shame that they've cheapened the whole Aston range by making the new XK8 look like a cross between the Aston and a Hyundai coupe.
