Koeni, I totally agree with you.

But yeah, I totally agree with the MX5 being the next MGB. They're just so alike, and, well, yeah :p
Honestly though, I don't see any modern Lambo being quite so prolific. Same thing with Ferraris. The 430, 458, Cali, and so on will just end up like the 328. Lamborghini really only has 1 that we think back to, 2 if you count the Countach, but still, I only ever think of the Miura, and that's when I actually do think of classic Lambos. All the current ones are too...
They're not unique. We've had what, at least 7 different 'editions' of the Gallardo, there were 2 Murcielagos revealed within a single week. I mean come on. The Reventon maybe.
