Oh you're a lefty? Well one advantage is that there don't seem to be as many fake lefty Fenders around.
Original AVRI with original case would expect between 1000-1200 Euro but if there are parts changed, its going to diminish in value. If the pickguard has been changed, the pickups could be too, even the body might be different. If these are the only pics you've got of it, would be a gamble
It depends on which year the guitar was produced. They used to have white pickguards and at some point switched to mint green. The one on the pic is Creme.
That was the transition year. Pickups changed so the poles are beveled now . Dot spacing got wider and necks got a little fatter
It could be, I fail to remember exact year for that switch. But around 2000 would be my guess for the last white ones.
As far as I know thus strat is early 2000. Good spot on the pick guard since you've mention it you can see a clear difference in the colours and pick guard.
I certainly wouldn't let a case determine my buying a guitar. Its the instrument that's important. However, those rectangular tweed cases are nothing special anyway. The chainsaw case in the picture will protect a guitar better, they are snug, designed to fit. Also those cases are far more desirable, as they are now hard to get hold of. You can't buy them new anymore, unlike the Tweed's..
Alright so the guard should be mint green. Rarely do people only change the pickguard only to stop there, most of the time pickups or other electronics get switched over too. So best to check under the hood to see that everything is legit. The potentiometers have dates on them which make it easy to see if the match with the guitars manufacturing year. The pickups should look like 57/62 pickups with beveled magnet poles. Inside of the neck pocket there should be date stamps also.
