Confused again

Today I went to Garage R not far from my house. They have about 20 FD3s on the yard right now.

I checked over a bunch of cars under $20,000. To most Australians that means the shittiest cars available, but in Japan 2000 dollars is a bad car. 20,000 means full tune almost perfection.

So the choice was. T04Z Top Fuel tune street registered perfection and 500hp. Brake upgrades, riding on Advan RS and S-tyres and capable of FSW in 1.54s. AMAZING! nothing to spend and you can drive it too the track.
Full aero too.

I also know of another similar car for sale right now.
I am soo tempted to push into this car or something very similar.

100% Race car. RE-Amemiya ADGT. T78 CE28N etc etc. Not good tyres and needed a Vmount
For me this is close but it's already got pieces I don't want.

But really my budget starts here.

Stock engine with a full RE-A aero. Custom light pearl with dry carbon parts! pretty nice actually but the high klms are troubling.

The problem is, they all have merits and bad points. Kind of the best one for me isn't there.
there were 3 spirit Rs and a pristine RZ in various states of tune.
How much is enough as a starting point.

Unfortunately the car I wanted to see the 20b FD was gone.
20b FC peripheral port??? NONONO

Japan offers way too much choice but it also means I know what I want because nothing matched.
I also noticed when I look at these cars, there are many things I look at and say... Do I really want to do this in Japan with no dedicated garage? Thats means a street car and not a 100% track car.

Anyway, It was good to go and see these cars, the stance, the impact, the small things you can see that the internet hides. It helped a lot actually.

Really it is soo hard to stay focussed because it would be sooo easy to change.
