It's a Volvo P1800 from late sixties/early seventies!
BTW: My first post here. Gotta love LFS, it's great! I have driven the demo more or less since S2 was released, then I got tired of it, and now with S2V I think I'm going to buy S2 any day!

Not really a test model, actually about 40000 examples were produced + about 8000 of the ES ("estate") version. At least according to Volvo themselves...
(BTW, My father is kind of an Volvo expert, and I have been to many Volvo meetings the past 17 years...)
But what is this (see attached)? Cars in background are Austin Healey 3000 and Lotus Elite, but I don't think that will help you much!
