Yes, 1996 was the last model year for the Roadmaster, but it was an extended run which ran to December of that year, which went into the '97 model year. The last Roadmasters from Sept. to Dec. 96 were still considered '96 models though.
Anyone who is "advertising" a "1997" Roadmaster doesn't know what they are talking about.
The last year for the Buick Roadmaster was 1996, Collectors Edition and all that.
No new full size sedan can compare in interior dimensions with the big modern GM B-D bodies. GM didn't realize how good they made these cars; hardly any complaints unless you had the TBI 350 and not the LT1 (then I feel sorry for you), but everything else in these big cars lasts forever and is very reliable. The interiors are hit and miss however.
96 was the last year guys, don't get it twisted. We will never ever see such real full size cars like this ever again. So take good care of them, do whatever it takes to nurture them back to life if you have to, as they are modern enough to be reliable for everyday use, and don't need so much in terms of maintenance, unlike the FWD Buicks of the same era.
The C4 Corvette then had 300 HP. Add the weight of this car and it can't be that quick. But as a big luxury car, does it matter?
I respect these cars too, but would much rather have the throttle body 350 as opposed to the LT1 with the troublesome Opti-Spark, reverse cooling system with the cam driven water pump that does nothing but leak. Spark plug wires are difficult to change, and the upstream exhaust headers are unnecessary.
Front-drive Buicks from this era really didn't require much maintenance either.
Park Avenues and LeSabres were just as reliable with the 3800.
That is until GM got careless and redesigned the intake.
