You should really pass on the idea of getting a 97. First model year had a lot of problems and the subframe is weaker than the 1998's and up. Just get a 1998 and call it a 1997
The other thing my car does not have that everyone else's seems to have is an external temp sensor in the front bumper. They added it right at the end of 1997 production. It allows the AC to work better and you can turn on OBC and the outside temp will populate in the cluster. On my car it just shows "---"
On the other hand, if you can find a 1997 garage queen with no miles on it and the original motor (doubtful) and with all the OEM equipment and spare and toolkit, etc. it could become an increasing value automobile at some point. Many of them have had their motors replaced under warranty though for D chunk cylinder wall issues, slipped sleeves, and RMS leaks leading to catastrophic oil loss.
