1986 Bertone X1/9 (Fiat) 21500 original miles. excellent condition

1986 Fiat X-1/9 Additional Info:

This is a 1986 Bertone X1/9, with only 21500 miles on it. The X1/9 is a Fiat based with Bertone doing the body. When Fiat quite importing into US the cars were change to Bertone and all badges were changed to read Bertone. Build date on this car is 10/1985. It has a 1500cc FI SOHC engine with a 5 speed transmission. Top can be stored in front trunk for open air driving. I purchased this car in June 1998, at that time it had 011688 miles on it, now just under 21500, that about 500 miles per year but in past 10 years it has been more like 50 miles per year. Selling because it needs to be driven. When I purchased the PO had stopped driving it because his family said it was unsafe, it was stored inside and not running. Clutch was not working and headlights would not go down, needed a slave cylinder and fuse and then all working.
Current concerns: Heater valve is not working so heat does not come on, I have new valve, it just needs to be put in.Driving lights shown in picture are not hooked up.Stain in front trunk, see picture 17, I do not know what this is and have not tried to clean.When adding gas it must be done very slowly, if not it will "burp" and spit gas back at you. I do not know cause of this.Has some paint over spray, see picture 18, this combined with PO comment about not feeling safe diving car lets me believe it had some body damage. All damage fixed but the front grill is not correct for this car. Will come with a Bertone shop manual
Correct VIN is ZBBBSOOAOG7158360 EBAY would not let me put this in.
