I don't think it matters who has had the car. Old lady? Did she keep up with the maintenance? Did the car just sit. Now if someone much younger let's say for the sake of argument (Mr. Wilson LOL J/K) well.... LOL... just picking on you I'm not trashing you... OK how about Nitrobasher... OK is that better..LOL...
But Mike had a point the other day. If they have over 150K many of the issues that arise when the car ages. (Parts that are going to wear out) have been replaced.
You are going to have some things go wrong. It doesn't matter what car you buy. The Mark VIII will cost for repairs if you take it to a dealer or shop.
If you can do them yourself, you will save lots of money. Still with LvC if you purchase the car and we can help you through many of the issues that your Mark VIII will have, as we've all had things go wrong. Plus, from reading other threads the owners are more experienced than the service stations on these cars.
I have 3 Mark VIII's and love them. I've had a bunch of things go wrong and have repaired them myself. Before LvC I was a car idiot (OK I opened it up for you Mr. Wilson LOL). Now I'm a car moron and moving up. But LvC has helped me learn a lot about cars and the Mark VIII.
What I have found out is, that the Mark VIII is not a hard car to work on plus most of the diagnosis from this site are correct. Plus you have many people who will help you over the phone while you are turning the wrench... (Thanks Ray)... And plenty others who are there to answer the questions.. Torquemonkey, 94m5, Jibit, Mr. Wilson, brentalan, ONEBADMK8, 1wykdmk8, MonsterMark, Marked8, Joeychcgo, Calabrio, Sergmark, JC1994, to name a few who have helped me from time to time.
Remember I have 3 Mark VIIIs highest miles 202K lowest 139K.. you will have things wear out from time to time. Mark VIIIs are great cars that are fun to drive, Class with some get up and go...
I don't think you can go wrong with any of he years. It doesn't matter whether they are LSCs or not (doesn't really mean a lot, although some think so just a few extra toys and 10 hp that doesn't show up).
98s have the best tranny, 93s the fastest, 94 bugs out from the 93s, 95 are suppose to be the slowest (although I haven't noticed), 96 finally got HIDs, 97 new toys and a different look from the gen 1s.
LSC got 3.27 gears, true duals and perf seats... what else...
All I know is that once you own a Mark VIII you fall in love with the car ask (MsM8tress LOL) and LvC helps keep the affair lasting..
Good luck with your 97 choice.. if the old lady 97 falls through you have a lot of nice offers from guys on the site. I don't know of any offered that you couldn't trust.
