Twin turbo VR4 3000GT 4wheel steering manual transmission

Mitsubishi 3000GT VR4 twin turbo project I picked up a few years ago. Was going to make this my daily driver but other projects got in the way. It is a 1993 in stock condition. Has not been started in a few years. Has manual 6speed transmission rebuilt along with new performance clutch assembly, and installed front transfer hub and shaft replaced because the splines were worn out. All this work was done by the shop I bought it from right after completion. Has a misfire on cylinder #1. I think it has a bad valve spring because sometimes ran fine and sometimes had a dead miss. I was planning on redoing the heads anyway because of the problems on these cars with the turbos causing valves to burn. I was also going to replace the timing belt at the same time because don't know when was done last. right rear quarter has dent and corner of rear spoiler is broken from an F250 hitting it in a parking lot. Has high speed auto adjusting front and rear spoiler along with rear wheel steering and active suspension, though I don't know if any of it works. does not have a good battery and I have not started it in 2 years. 4years ago I drove it 10 miles to where it is stored now and other then moving around on the lot it can't have more then 100 miles since transmission, clutch and front driveshaft were rebuilt and replaced. As Japanese super cars become more sought after it is the perfect time to buy, both my Toyota Supra's I sold 10 years ago have seen an appreciation of over 80% what they were sold for at that time. It is a solid project for a correct and unmodified twin turbo "Corvette Killer". I hate to turn over this project to some one else realizing the value like the 308 Ferrari in 2010 but with my with little kids and 5 other cars in restoration stage decisions must be made. please ask questions and understand the value of this rare car.
