I think this is pretty self-explanatory. The Astre was simply a rebadged Vega, while the Monza was basically a mildly-restyled Vega with a new name--and initially just a trim level of the Vega. Best to avoid duplicity. Jgera5 (talk) 04:28, 25 March 2014 (UTC)[reply]

• Oppose While I agree with what Jgera says about the Astre and Monza, there's a lot of model-specific detail in all three articles and merging would produce an article that's too long and clunky (contra the merge guidlines). Writegeist (talk) 20:26, 25 March 2014 (UTC)[reply]
• Split I support the merge of the Astre into the Vega article; but I oppose the Monza merge. VX1NG (talk) 17:51, 27 March 2014 (UTC)[reply]
• Split I also support the merge of the Astre into the Vega article; but I oppose the Monza merge. OSX (talk • contributions) 08:30, 29 March 2014 (UTC)[reply]
• Oppose I feel there is little to no need to merge these articles. They've been fine on their own without any problems, and if we're going to merge articles based off of other vehicles, we might as well just merge every single Pontiac model since 1980, almost all of which have a twin. I don't think any merging is necessary. GG360 (talk) 21:19, 1 April 2014 (UTC)[reply]
• Support the merger of the Astre into the Vega article. These are essentially identical vehicles except for the rebadging and their marketing campaigns. Once the redundant material is removed, the single article will not be too long or clunky. On the other hand, the Monza is second-generation of the Vega platform with similar badge-engineered equivalents (1st-gen Pontiac Sunbird, 1st-gen Buick Skyhawk, and 2nd-gen Oldsmobile Starfire) that should be merged into one article.

• Oppose The Astre started as a Canadian-market variant and was only marketed in the US later. Also, as GG360 stated, Pontiac was basically a badge-engineered brand from 1982 onward, with its only truly unique offering in this country being a badge-engineered Holden marketed here as the GTO.

• Oppose The Chevrolet Monza was always marketed as a distinct nameplate and always treated as a separate model by Chevrolet. The fact that mechanical components were shared extensively between Vega and Monza does not make the car a subseries of Vega by default.

Comment: I would like to clarify and modify my response from earlier this year. The proposed merger would cover the entire platform and models. However, it seems there could be several approaches and thus the differences in splitting or merging. I think the following suggestion is most "supportable":

• There are currently separate articles for the Chevrolet Vega and the Pontiac Astre. If the guidelines that have been established for articles related to rebadged versions of cars, the two WP articles about the Vega and Astre twins should be merged into one article. There does not seem to be any historic, geographic, or marketing segment significance to keep two articles about these identical cars. The resulting merged Vega/Astre article would not be long or unwieldily.

This automobile platform subsequently evolved into the Chevrolet Monza and was also used for three more versions (1st-generation Pontiac Sunbird, 1st-generation Buick Skyhawk, and 2nd-generation Oldsmobile Starfire). These have separate articles. Thanks! CZmarlin (talk) 01:46, 1 December 2014 (UTC)[reply]

• Split as per VX1NG and OSX.  Mr.choppers | ✎  02:23, 1 December 2014 (UTC)[reply]
• Oppose Though see no reason why the Chevrolet Cosworth Vega can't be merged into this. Warren (talk) 21:07, 12 January 2015 (UTC)[reply]

• Split as per VX1NG, OSX and Mr.choppers and I agree with Warren about Chevrolet Cosworth Vega being merged into here and I support the merge of Pontiac Astre because it was a twin to the Vega but oppose the merge of the Chevrolet Monza because it was a different car despite being mechanically related to the Vega. As CZmarlin said the Monza had its own siblings which were the first gen Pontiac Sunbird, the first gen Buick Skyhawk and second gen Oldsmobile Starfire, all of which have separate articles. There's no reason in my mind to merge Chevrolet Monza into Chevrolet Vega.--Kevjgav (talk) 22:49, 24 May 2015 (UTC)[reply]

Comment: I see no reason why we can't merge Pontiac Astre and Chevrolet Cosworth Vega into the main Vega article and merge first gen Pontiac Sunbird, first gen Buick Skyhawk and second gen Oldsmobile Starfire into the Chevrolet Monza article. With the removal of any redundant information, the resulting articles shouldn't be too long to read comfortably.--Kevjgav (talk) 11:26, 25 May 2015 (UTC)[reply]
