Check Engine Light & Exhaust Buzz

Okay, I put this in another post in another forum, but I wanted to get some more opinions...This is on a 92 SVX...I just want to know if you would buy this car with these issues and mainly if the CE light is a big issue. I know one issue is that if it's not fixed, you won't know when something DOES go wrong.

"There are a couple non-issues that someone might decide they would rather have taken care of - one is the 'check engine' light on the dash comes on intermiitantly: it's been that way for years; I had the dealer evaluate it and was told that when they hooked up the computer to it, since it was triggering error codes randomly and with no pattern, then they decided it must be a fault in the wiring harness and it was up to me if I wanted them to perform electrical diagnostics to see if they could pinpoint ithe source of the false errors. Since such work could take hours, I decided it wasn't worth it, and that I'd live with the light.

The other one is in one of the exhaust pipes - when the tach is exactly on 2k, and only 2k, you sometimes hear a buzzing sound. This comes from the fact that inside a sealed area in one of the exhaust pipes is a section containing baffling, and one of the baffles has come loose, and as the air passes through it, at a certain speed, it causes it to vibrate at a certain harmonic. When I had this looked at, they told me it was again my choice whether to replace it for a few hundred bucks (dealer cost; I'm sure it's a lot less with used parts), or to just live with the harmless but sometimes annoying sound. So since I wasn't going to drive it terribly often, I chose not to spend on the replacement. This also was several years ago."
