That was actually one of the cons against me getting a Lexus IS.
My current car is very rare - since there's only a few hundred Alfa GTA's in the country.
The first one I ever saw I bought, and I haven't seen one since except at Spring Italian day, where there were only about 4 in the midst of thousands of Alfas, Ferraris and Lambos.
On the other hand, the GTA is an Alfa, and they are common enough.
The lexus brand as a whole is much less common than Alfa.
At the same time, again the Alfa 156 is fairly common, and the GTA is a derivative.
(Although not much of it is the same - Nearly all of the body panels were changed, and the chasis is completely different. That's before you even get to suspension, brakes and engine)
As I wait for my IS to arrive, I keep getting quite mopey every time I see my old car parked up anywhere.
I'm really going to miss it a lot.
