Laudoracing GTVs with the wide fenders but I think the stock body design is so good that those big bulges interfere with it rather than enhance it.

As far as the SZ, its styling is a little too unconventional for me.

The only 1/18th Alfas I'd consider buying at this point are the Welly 8C that I sold, a good boat tail Spider, a specific T33 racer they haven't made yet, and a GTV6 in a race livery that really appeals to me like this one: link to photo

I do have another Solido GTV6 on pre-order in a better version of silver than their first one.
