Tips on Buying Cars: Buying a used rx-7, mazda rx 7, dealer id

Question
I am looking into buying a used mazda rx-7 that looks like a really awesome car.  This is my first time buying a car and I do not want to make a poor investment.  If you can, please tell me if the car's price is reasonable, if its age could be a factor, any problems this car could have, and anything you think I should know before purchasing it.  The link to see this car is :

Answer
Ok first sorry for responding so late but I was away. Ok I looked at the car and it is certainly sharp. But.... there is no car in the world that I can think of with 160,000 that I would buy. Dream cars excluded. I am speaking of everyday drivers. This car has 160,000 miles on it no matter what the motor has. Also you know as well as I do these cars were made to drive fast... and hard. So in my opinion I wouldn't spend 15,000 on this car. If you want a hot car spend the money on a nwer honda or other import that is used, and then make the mods yourself. You will never recoop the money spent on this car or almost any car for that matter cars are not, in most cases an investment tool. They seem to always go down in value. I hope this helped you, if you have any other questions please ask. And please leave me feedback. Thanks
