I'd say 48 is way too high like the others.
They are out there, do you want red? or some other color, Targa or coupe, 3.0 liter or 3.2 liter.

Your stick issues should pass with time.
Lots of good information here. I agree with Mlambert - a 95 with no accident history and 14k miles is a rare bird indeed. MLambert also mentions that 48k might not be a bad deal if all the maintenance is up to date. That's a big qualifyer. You have to make sure that the maintenance is up to date at that price.
Also the red 1991 is also a fair deal at that price assuming of course the same thing - maintenance records.
This black one is a good deal here with 55k miles and lots of work done - but there may be issues there as well as in the time that has gone by with the TB/WP.
48k for a 95 without good maintenance records is NOT a good deal. 33,800 is not a good deal for a 91 without good records even though the mileage is low. If you buy a low mileage car - and believe me I had this issue in front of me when I was looking but the salesman thought he had a "one in a million" and worth all kinds of bucks and it had no maintenance history cause it had never had any maintenance cause the previous owner thoght that the mileage was so low that "why would it need anything" - Obviously not an NSX officianado - right. A looker not a driver or a serious car owner- but really who would spend a lot of money on a car that never got driven - except to maybe change the oil or something - answer - no one would. Unless a person drives his car the liklihood that person will do all that expensive maintenance is very very slim.
So what do you do - you asked if a PPI is as good as being there - if you have confidence in the owner after talking with him and you have a good PPI done by a really qualified mechanic then yes that will do. I sold my 993 to a guy in California that way. So yes is the answer to that but you have to have a lot of confidence in the person you are dealing with and now I hear from the guy that bought my 993 yearly. We still talk and that's been 4 years now. You can develop a considerate friendship with a person by phone and email. I do it all the time. I have a lot of friends on Prime that I trust and that I consider to be good buddies - that's the way I am. It's never let me down and I'm 61 and have bought many a car and sold many a car.
So the two nice low miile models you show are most likely the kind that the salesman is hoping to find the guy that is just crazy over the car and just has to have it at any expense. He's hoping to find someone that will listen to his sales jargon and not know anything about timing belts, water pumps, hoses and time and intervals recommended in the service manual.
Chances are with only 8000 of these cars sold you may not and probably won't find one owned by an owner that is close by. You might but it's not too likely and not one with low miles and great maintenance history.
You say you'd like to spend 30k - so why in the heck are you looking at cars for 48k? That's way out of your comfort and price range - don't look at that car anymore. Look at cars that are close enough to your budget that you could actually afford to buy it. Even the red 1991 - has no service history so you'd immediately have to spend about 4k on the car to get things up to date. TB/WP/Hoses/all fluids changed/plugs - just a thorough going over. Maybe 3k to 3.5k on maintenance - and even at that a super low mile 91 that is pristine is most likely worth 35k+. Yep it most likely is. Is that a good way to spend your money - well I think it is but you have to take that car to someone that you trust to do the job and you gotta do it when you buy it. I'd offer the guy maybe 31.5k and you'd get a good car. Now is that as good a deal as buying one that has had everything already done to it that has say 50k miles for say 33? Well you be the judge cause that's what a nicely maintained 91 with 50k miles and all maintenance done is worth - about 33k. Maybe you coud see you way to paying an additional 4k for super low miles -but remember it's not just the tb/wp/hoses that might get you - how does that AC work after all this time and no use???? That could cost you big. So these low milers are not without their pit falls.
But there is no substitute in a lot of ways for super low miles cause you can never turn the odo back - well not legally. If you know what I mean.
Good luck,
