The back and profile of the 73 is nice but the nose (standard or Laguna) is, well.....ummm....interesting. After 73 the Chevelle styling went south...in a hurry. I would much rather have a Monte, Regal or GP from the 70's. On the other hand, 78/79 Malibus (single headlight) are very clean looking and have some decent lines. I've seen a few of these with the Monte SS nose that look really cool in PT style. I may be wrong but I think they're lighter too. Just my .02.

Yes 78-82 with right drivetrain are easily in the 3200lb area.73-77 are more in 3800-4000 stock
