You will need to be a good welder/fabricator to take that on. The delta was a good car in its day but I think the 1300 engine will be a bit disappointing. The fact that it has cooling issues would be a concern for me. Lancia made great engines but they are not strong. I've been looking for a good beta coupe for a while but they are like hens teeth. The paint does a good job of hiding corrosion right up until it's too late. If you could get it to a good condition though, it would be worth a small fortune.
