Beautiful car. Welcome to the forum. I bought a 1997 with only 40K miles on it and had the same concerns. I decided that peace of mind and dependability were my biggest concern. I had my local indy mechanic drop my motor and I did the EPS IMS repair (see attached video) While he was @ it I had him change every rubber hose, the water pump (was already starting to get some play), Plugs and plug tubes, fuel/air/oil filters, Air/oil separator tank, rear main seal, front engine mount, transmission fluid and any other thing I could think of that would leave me on the side of the road. I spent about $2200 on all of this between parts and labor. I have since put almost 5k on it and she is purring like a cat. I have no reservations about jumping in and running up to the mountains and running her hard.
Here is the video:

Have fun and play hard with her.
