I saw my first NSX in 1991 at the Texas state fair. But the stealership had a markup on it bringing the price to $85K or about $140K in today's dollars. I was disappointed and forgot about it for 18 years. Then my wife got cancer. And on a visit to her doctor, he happened to pull into the parking garage next to us in his Sebring Silver 1991 NSX that had well over 200K miles on it and looked like it was still new. A couple years passed and my wife was still fighting cancer. She told me that she wanted me to buy an NSX because as we were finding out, life is too short and we can afford the car. It was her gift to me and a way for me to get away from her medical situation for an hour to drive or clean the car. My therapy.
I posted the following on another thread by someone just like the OP, looking for the dream car. I hope it's helpful.......
I had never driven an NSX until I flew out to purchase my first one, a one owner 1991. I guess I was saving myself for the right NSX. If you are taller than 6' 3" then you will find the car a tight fit. The man I bought my current 2002 was 6' 3" and he fit but, was tight on head room. There are many large people who find the NSX comfortable. If you can't find someone to let you drive theirs, just find one that you are serious about buying if all things check out. I won't buy a car that I can't test drive and you shouldn't either. The seller will know how serious you are by the questions you ask him or her. Detailed questions that only one who knows what to look for in the car. For example: Timing Belt and Water pump replacement, or if it's an early NSX, is it within snap ring range and ask if it has all of the maintenance records, etc. Tire kickers won't do the research.
Since I brought up research, it will serve you well to study the NSX wiki which you will find on the menu bar above. I did it before I bought my first NSX and it helped me be able to judge whether the car I was looking at was worth buying.
I purchased both of my cars from Prime members. I purposely stayed away from dealers as they were not willing to negotiate and most knew nothing technical about the car. With a private seller it will be easier to workout a deal for the car. It took about 4 months to find the right car. But, remember you are buying a car that is now in demand and it's been a seller's market. However, there are still some deals out there. I've bought both of my NSXs out of state. So, for me, my comfort level with the seller is as important as the condition of the car. I spoke to the sellers of my cars and got to know them a little. True car guys don't mind talking about their passion for cars. Once you get comfortable that the owner is trustworthy and he knows you are a serious buyer, ask for receipts for the major maintenance items like TB/WP. If you are now comfortable with the car and the seller it's time to go see that car and drive it. Also, before you go be ready to buy the car on the spot. Too many folks on here and the NSXPrime Facebook page complain about losing a car because someone else came in with the cash before them. Most sellers will sell the car to the first person with the money. Once you look the car over, you might want to have a PPI done on it. I didn't have one done on either of mine as both cars came with complete maintenance records going back to the cars delivery at the dealership. Both of my cars were purchased way out of state and I drove them both home from the seller. I won't lie to you, buying a car out of state is a little scary. However, if you do your homework and have the money ready to exchange it's not a bad experience at all. Being willing to look out of state will expand your chances of finding the perfect car for you. I highly recommend that, if you have the time, you drive the car home. It's miles of smiles and a good way to learn your car and make a list of the little things that you'll want to fix or change. Plus it's an adventure you'll never forget.
I would add, that it sounds like you are having to save and work overtime to get your dream car. I'm not trying to discourage you from buying your NSX. But, there is the reality of actually owning one. Owning an NSX is a pay to play affair. They are not typical Hondas. Though they are very reliable, parts and service on an NSX is much more expensive than an Accord or even an RSX. You are buying an 11 to 25 year old exotic car with bespoke parts that are getting harder to find thus rising in cost. Now, an NSX is a lot cheaper than a Porsche, Ferrari or Lamborghini among others to maintain. So make sure that you set aside funds to make those repairs. And don't do anything on the cheap. With the NSX it will cost you more in the long run if you use cheap ebay parts. There are some good aftermarket parts that are made by folks that either own an NSX or are very knowledgeable about the car. But for me, OEM or JDM is the way to go when you can.
I know this is more than you asked for but, it was my first NSX driving and buying experience. That first drive of the car I was going to buy is a memory that I will always remember every detail of as if it was yesterday. And since I took my son with me, who was 12 yrs old at the time, the long drive back was a great adventure that we share. Good luck in your search.
