What to look for in a '74 1.8 Options

[era vulgaris]

I've come across what appears to be a very nice '74 1.8 for sale not too far from me. I'm currently trying to make arrangements with the seller to view the car. He claims it has no rust (we'll see!), excellent paint, excellent running condition, and he has records going back to the original owner. If all is true, it'll be a great deal for what he's asking, and I'll be able to replace the nightmare Scotty Boy sold me.

Aside from the obvious stuff (rust, etc...which I've learned via the school of hard knocks with my car)...is there anything specific to that model year and engine size that I should be aware of? The car does have its original FI.

Here's my other question...is a 1.8 worth buying? From what I understand it would have less power and torque than my 72 1.7. I'm not unhappy with how my 1.7 performs, so would it be a real noticeable downgrade in performance?
