Thanks, Rich. I'll try to find out when they (variocam, belts, .. ?) were last replaced or checked. I'm expecting it to have a fairly good service history, so hoping for the best. I've been reading about the variocams losing teeth after only 50k miles or so. Don't really know what to look out for (though I've read some buyers' guides). Main things, I suppose are: rust, strange noises which might be dodgy variocam.
I remember reading that these cars (later 944s and I assume 968s too, but not early 944s) have some sort of problem with the brake mechanisms - plate lift. Is that easy to check for (without taking off the wheels)?
I got my 2.5 only 6 months ago, and have enjoyed doing about 3000 miles in it so far. It goes really well, and I really like it. Would be happy keeping it for a while. It's just that I sudddenly have a bit more money for a car, so thought I might look into something a bit more powerful. Not keen on a 986. I quite like the Carrera 3.2 911s (mmm

So 968 seems like the one for me... will let you know how it goes.
