I have had a bunch of Spiders... just beginning to tackle a restoration on my 77 (probably this spring). carbed 80s cars have about 80hp.. injected 102. Not a lot by todays standards.. but they do not weigh much and have a tight ratioed tranmission and diff that makes for rapid acceleration and not much top end.. not that you want to do 100mph in one with the top down (been there, done that, got beat up by the wind)
They have a very sweet engine as long as proper maintance was done (especially the T-belt around every 20,000 to 25,000 miles) A great feeling (if weak) transmission, and still the best soft top in the business. It's ease to put down and take up will put a miata to shame.
80s models are less prone to rust than earlier ones.. and most electrical problems come down to the grounds.. especially the taillight ground in the trunk. If it has a bad connection.. all sorts of funky things happen.
Interior is a bit weird with the driver having to assume an "ape" position with long arms out to a wheel inclined like a bus with your knees bent as the pedals are a bit too close.
These are a vastly underappreciated classic sports car. They can run rings around most of their competition and what they couldn't.. they were more refined than. The twin cam engine is a real jewel with a distinct and pleasant sound and a bit more punch than pure numbers will tell you.
