Great looking model of a fantastic car. I had seriously considered buying a used one back in the early 90's but kept worrying about the maintenance costs. Instead I bought a slightly used Supra Turbo that ended up being the most expensive car to maintain I have ever owned.
I had looked at several 944 models back about 10 years ago when I was seriously considering getting one, but the cost of maintenance always stopped me.
You might want to do an Internet search for a Porsche owners forum and see what they have to say.
I think I remember seeing pictures of that Corvette on another forum. If I remember correctly it was a 1/8 scale 1985 Corvette that was highly detailed.
