That was true for '87 and '88. From '89-'92 it had the same dimensions as the Deville/ FWD Fleetwood. These years also added the 22 way power seats. In '93, the 60 Special was last year's Fleetwood, with the seats as an option.Katshot said:And it was just a slightly stretched FWD Fleetwood.
From '94-'95, the Deville had the 4.9L, while the Concours had a 270HP Northstar (275 in '95). From '96 until '99, the Base had the 275HP Northstar, and the Concours had the 300HP version.
Some of the major differences b/w Deville and Concours:
In '94, the Concours had road sensing suspension, a 11 speaker system, 16" (vs. 15") rims, and monochrome side moldings and bumpers.
In '95, there were a few minor improvements, such as formerly optional tration control was now standard. Concours now had a Integrated Chassis Control System for brake performance and stability.
A bit of changes in '96. More powerful PCM, mass airflow sensors added, better fuel injectors, and ICCS now standard on the Base model.
Concours also had Magnasteer, rainsense wipers, and Continuously Variable Road sensing suspension.
There was a restyling in '97, with a d'Elegance model now between the base and the Concours. Concours is now 5 passengers. New features was side air bags, and standard Magnasteer on the base. d'Elegance and Concours had a personal memory package, and Concours had Stabillitrak.
In '98, Stabillitrack was optional on the lower 2 models, and RDS radios were standard. Concours had an improved Magnasteer system that also reacted to lateral acceleraton (Yaw control I think). Heated seats were standard on the top 2 models.
Not many changes in '99. The top 2 models had optional massaging seats.
Probably missing a few important points, but after typing all that, I don't want to be here for a while. :wave:
