I've seen plenty.
As for the Diamante sharing a design with the early Lancer...Mitsubishi was doing something called "Brand Identity". Ironically, Nissan did it with the B16 Sentra's introduction, basing cues off the 04-08 Maxima. Put an 04-05 Max next to a +07 Sentra...and it's obvious, even with the facelifted Maximas of 07-08.
