Thank you for the reply.
I'm sorry, I just thought there were some price guidelines.
The car itself seems quite modern to me, it has electric windows, remoteless key entry, a new roof (the spider is a cabriolet) and airconditioning.
When I read about engine specifics it said that this engine is so upgradable that it was later used as a 2.0L turbocharged for Alfa-Romeos in the 90s.
Seeing that the Fiat Spider I've seen has a 2.0L engine, I recon the only difference between them is the turbocharging.
Do you know if Fiat parts are commonly used and easy to replace?
