This sounds like a pretty good car from the ad. It has a late model FI engine, so it's MPG and reliability is going to be about as good as it gets. The price is really quite low for a built car.
A word of caution, you can really get burned buying a car someone else built, especially if you're not familiar with these cars. It's only as good as it's builder. From what I can see, this car looks pretty well built but you never know for sure until you see it in real life.
