First time
 

I am a BIG fan of the Preludes from 1988 to 1991. I believe that is the period of time when that body design and fuel injection were in each car. Prior to 1988, is it true that an engineering degree was needed just to figure where all the vacuum hoses and hoses in general went?
I am hoping to get some hints as to what to look for when deciding if one of these vehicles is worth purchasing. Rust on the rear quarter panel, just in front of the rear wheel seems to be an easy one. Mechanically, what are the red flags.
I hope I'm in the right place for this post
