You could build a Rx7 for about 50p these days, they are breaking them left right and centre as their value has just gone and unfortunately having just moved from Rx7's, the community is getting...well shall we say, Impreza like.
The Supra is about the only jdm sports car from that era that is holding its value.
I said to the Rx7 specialist i use, the only way i would ever get back into one is if it was built from scratch, new everything, ironically he has an absolutely brand new shell he bought from Mazda sat in his workshop for sale, very tempting One day, but not until their is some value in them again.
