The LSS, based on the "H" Eighty-Eight body, was and is a quiet, economical, comfortable daily driver. I put nearly 1200 miles on mine this week, and loved every one of them.
I am sorry that you dont enjoy yours as much as I do mine.
However, I should point out, that those 74-76 Delta'* were land yaughts which handled like tuna boats in high seas. The 80'* New Yorkers (fwd) were mostly K-car derived, luxury car wanna be'*.
I used to sell them occaisionally, and if you could over look the little 4cyl screaming away (turbo? oh no!!) ...and the cheap interior, shoddy construction and unreliable nature of the car....you might appreciate the cheap price you had paid for this treasure.
As for the Regal, I've ridden in that particular model...and unless it was Buick'* Limited or better yet, GS...they really were just basic family transportation. The only good thing about Buick'* version over the Olds...was that the Regals got the 3800 I believe, while the Cutlass had the 3100.
I really enjoy the seats in my LSS. They offer me good lateral and lumbar support...far better than any bench..thats for sure. I find the car to be quite pleasant at all speeds...and gives excellent fuel economy. Although Olds recommends 30psi for the tires...I run 35psi which aids handling I feel..and really doesnt detract from the ride quality. These GoodYears call for 44 cold.
If you dont enjoy your car...you could always ebay it...as there is always a good market for nice LSS'es.
