Hiya Nick
Welcome to the proper part of the forum [

Any decision to look at an SC for sale is a good one. But bear in mind these cars are only affordable 911's if you buy the right one to start with. Buying the wrong one costs bucks in the long run so get your head used to the idea that you should buy the best you can afford. Include the cost of a decent PPI in your budget - you cannot afford to buy your first 911 without a PPI.
I take it from your post regards leaks that you are looking at a Targa. Targas with good seals shouldn't leak - they don't 'all do that'. Get your seller to run the hose over the car and sit in it with the windows closed to see whether it does or not. Seals aren't too bad from Porsche - leading edge seal on front of roof is a tenner for example, the windscreen pillar and top seal is over £100, window seals about £80 a piece IIRC, so if you have a leaky roof then get cash off to pay for sorting that.
What else are you looking for? Rust is what you are looking for first and if you find a load (and even if the car is CHEAP) move on to the next one, there are PLENTY of cars out there. Look by fuel filler flap, around headlamps, behind battery, in front panel (under where the bonnet latch is). Look in door shuts by door latch, at bottom of b-post. Jack car up and support on axle stands & take front and rear wheels off to look up under the wings into the extreme corners. If the car needs pressure washing to get accumulated crud off then have it done - that crud could be hiding the number one thing that will cost you cash.
Mechanically they are generally ace, look for problems with crunchy gearboxes from 1st into 2nd and 2nd into 3rd - should be no noises and if there are then it's gonna need rebuilding at some stage. Minimum £1500 including removal. While that is out you will be doing clutch so add £300 for that. A heavy clutch pedal (they are not all that heavy when right) means clutch on the way out. Budget £900-1000 to do that but as I say if it's coming out then you will be rebuilding the box if it's not already been done so factor that in.
Otherwise you are looking for oil leaks and usual engine stuff. Try to drive the car until it's nice and warm - so 15/20 miles minimum. Turn it off when you get back to the seller's location and leave it sit for 20 minutes or so and see how easily it starts - hot start a common problem on these cars and a pig to track down sometimes.
Also deduct money for cars with no Fuchs, cars with cloth trim, cars with little specialist history in last few years etc. Older SC's can also be very prpice-sensitive when it comes to colour and trim, so if it's not everyone's cup of tea then knock some wedge off for that too.
The nicest SC Targa I have seen in the last 12 months was Tim's. That was RHD and had everything done - £2500 respray, SSI's, spotless Fuchs, Carrera tensioners, rebuilt top, poss even Bilsteins and sold for under £10K which was criminal. If the cars not RHD and MINT (and I mean absolutely mint) then work back from that. Distinctly average SC Targa currently 7 grand and no more but they do sell for less, especially if 180 bhp - don't let the sunshine cloud your judgement!
Tell us more about what you are looking at for additional feedback, some pics would be nice. Are you buying from a club member, we might know the car. What is the budget, let us know.
Cheers, JG.
PS: Oh, the easiest way to tell a 204bhp car is if it has wing repeaters. 204bhp came in August 1980 for the 1981 model year so could be either.
