I have a '92 SC400 I bought used in 2002, without a doubt, it is the best car I have ever owned. The previous owner had changed out the sound system and replaced it with an Alpine system plus he replaced all the speakers with Boston Acoustics. There is no guarantee you not not experience any problems with the car you are considering but I can assure you the likelihood is low. The SC is a sneaky fast car and the faster you go, the faster it wants to go. Handling is superb.
