91 XJ Pros and Cons?

Thinking of getting a 91 XJ Laredo, Auto, 4.0L. What are the pros and cons of this specific year?

Also, the guy selling says in order to start it you have to push forward on the transmission shift lever because of a problem with the safety switch on the auto (so you can't start it in drive, etc). Would this be a heard thing to fix? He says it has something to do with the switch, but hasn't fixed it yet.

Thanks for the help.
