“Coach Insignia” is a Fisher family label.
The Fishers were the founders of the “Fisher Coach” company, which built the original bodies for General Motors cars [about a century ago], and which was subsequently purchased by General Motors.
Their wine operation is a little unusual by California standards, in that they have a parcel down on the Napa Valley floor [where temperatures are much hotter], from which they make the “Coach Insignia” red, but they also have an estate way high up on Spring Mountain [where temperatures are much cooler], which produces most of their other wines.
So their “Coach Insignia” is a much hotter, softer, fruitier, more “Parkerized” wine than the “leaner” or more “European” wines which they make at a higher elevation on Spring Mountain.
Anyway, since you like Caymus and “Coach Insignia”, I’d urge you to take a long, hard look at Australian or maybe even Italian “Super Tuscan” Cabernet, for wines that you might enjoy at the $40 price point.
Sparky Marquis [and his “Mollydooker” label] is always the place to start for affordable wines in that style, and “Maitre D’” is his basic Cabernet. Just looking at Cellar Tracker though, people really like his “Enchanted Path” Cabernet/Shiraz blend:

And if you like Caymus & Fisher Coach Insignia, then you really ought to try some Barossa Shiraz.
In addition to Sparky Marquis, I can just about guarantee that you’d love the wines of Chris Ringland:

I don’t know whether he’s still involved with the “Three Rings” label, or whether he sold his interest in it. He’s been through an assortment of different labels in the last few years [which may or may not still exist] - if you can find his “Southern Belle” wines, they’re partially aged in old whiskey barrels, which produces some of the craziest flavors I’ve ever tasted.
Anyway, Sparky Marquis & Chris Ringland are on the short list of the very best winemakers in the entire world - even if you hate Parkerized wines [you have to admit that they know what they’re doing] - but especially if you love Parkerized wines.
