I am an 80's car fan and have always wanted an Eldorado or Seville (slant back). I have found two models I really like. Both are very clean, appear to be well maintained mechanically, and are priced fairly. The Eldo has 115K on the original engine -- I say original because I really don't know but am trying to find out. The Seville has 53K on the original engine. I would like to buy an 80's car for light errands, some weekend travel, etc. I have considered this purchase before and did not buy these models. I went with an 88 Deville, which I love. I am afraid of the HT 4100 engines ... and just would not want the headaches of replacing a motor or dealing with the engine knock, etc. Yet, I cannot get the Eldo body style or the beautiful slant-back Seville out of my mind. I can't say I like the 80 Seville (different engine) or the 1979-80 Eldo because the models I see are definitely showing the age difference from the 85's I am looking at now. So, what would you do? Take a chance or maybe opt for a Riviera or Toronado from the same year? Would you just recommend NOT getting the 85 Eldo or Seville no matter what? I appreciate your insight, as I am new to the 80's Caddies.
Thank you very much ... Happy Father's Day to all reading!

Re: I'm afraid to buy these cars ....
Happy fathers day to you also.Many here will advise you stay away from the 4.1 liter engine for the reasons you mentioned and save yourself future problems.The slantback Caddys were a unique body style indeed---definitely a personal choice to own when in original production.Every now and then i see one on the road and they really stick out in todays era as there is nothing comparable to that body style presently.
The 4.1 liter engine was a true blunder by GM.Shortly after these were produced and driven by customers,Cadillac dealerships throughout the country had stockpiles of these flawed engines to deal with.GM redeemed themselves with improvements on the 4.5 and 4.9 liter engines.
