"harde auto" means as much as "rust free" (you don't pay extra for the rust )
Did the seller give you any info on the engine and transmission
Like mentioned, 72 means a 1.7 fuel injected engine and a tailshifter transmission
The side shifter tranny is often called a "2 liter bak" in Dutch.

A side shifter does shift better (less vague) than a tailshifter.
Still a lot depends on the shift bushings etc.

Don't rush into anything you're gonna regret.
You seriously need to educate yourself about these little cars
Go drive a couple. Try different ones. Don't be lured in by the price (a low price often has a reason)

You'll often find that the owners/sellers know as little or even less than you do about these cars and they will come up with all sorts of bullshit stories and make-believe-upgrades which are usually down-grades or crappy repairs...

Nope he didn't mention anything about the transmission (I never asked anything about it..). But I'm still waiting for his reply to my question if I could come over and take a look at it.

A question I have here: the specs page on this site (914 Info) says that there never was a 1972 2.0 4-cyl ? Production of this type started in 1973, right ?

All I can do for now is wait for answers. I also found a few cars in Belgium, inlcuding a six-cylinder for 6500 euro, the only problem with that car is that it seems to be disassembled for I reason I do not know (yet). But the seller does claim that it has a re-build engine. Is there any way of knowing whether it is indeed rebuild or not ? Just look at the "cleanness" of the engine ?

Nope... Unless he has an invoice for the work done on the engine, you won't know
Know that any 6 cylinder will have a mileage of between 1:5 and 1:7 (1 liter to x km's)
Also, if you need to rebuild that engine, count on doubling the price of the car

cheers,
