Before buying this car, I read a very comprehensive article on IMSB, learning the '99's have less than 1% failure. When this car came available, I asked the seller if he had the IMS replaced. He said no, that his indy echoed what I knew. I wanted peace of mind, so as soon as i got it home, I made an appointment with a trusted indy. The car needed mounts, and when I went to see him, I said I wanted the IMS replaced. He told me what I already heard and read. "I'll take your money if you want me to, but I'd shine it on".
A week later, the drive side CV Joint blew up. The indy told me the drive train was in good shape.
So I've spent the legendary ~$2.5K on repairs.
The car runs great and has buttery smooth shifts. I'm sinking coin into suspension, as it's all original, and am addressing minor cosmetic details and have done some hacks.
Waiting for them to reopen the roads...
