Yeah, I like this week's pic..
In 1986 GM shifted the coupe and sedan models of the LeSabre to the new H-platform FWD, the same one shared with the Olds Delta 88 and the '87 Bonneville. Seeing the upcoming demise of the RWD G-platform, and also seeing a chance to capitalize on the success of the turbo Regals, Buick made an interesting choice and applied performance measures to the LeSabre, a car with a history of being a big-ass land barge.
First, in '86, came the LeSabre Grand National. No more than 117 copies were made, making this LeSabre one of Buick's rarest models ever. Packing the 3.8 V6, this was mostly a looks package, with the requisite black paint and black/grey interior.
Starting later in '86, the T-type LeSabre came to market. Similar to the LeSabre GN, the T-type had a few color options, a different nosecone with front spoiler, rear spoiler, and different taillights. Paired up with Buick's "Gran Touring" suspension package and P215/65R15 Eagle GT+4 tires, the LeSabre T-type surprised many a critic.
GM, though, in typical "shoot-themselves-in-the-foot" fashion, decided that sporty and badass were not to be for Buick, and in '90, pulled the plug on the T-type. The LeSabre returned to it's large, wallowing ways, and ultimately was killed off in 2005.
So, what to do with this little FWD surprise? The first answer is obvious...shove a L67 3800 V6 with a blower in it and really have the fun Buick intended. But, what about a Northstar? Maybe an older Caddy FWD V8 from the '80s? LS4 from a late-model Impala SS? Hell, they're probably cheap enough, why not convert it to RWD and make one a correct GN?
