I don't know if anyone remembers me; I was fairly active last year...the 97 Bonneville, between the P0172 and the leaks...I finally gave up and have been working on saving up for a new car. Still own the 97, but haven't touched in a few months.

Found a 99 SE locally for 4000...102 thousand miles on it.
Was trying to find the main differences between the 97 SSE and the 99 SE..obviously SSE having more options, but what more options? What will I be giving up?

you will gain some hwy fuel economy because of the different gears, the suspension is a little less stiff and most dont have the air ride. thats all i can think of besides the obvious goodies.
