well a running SA (79' and 80' rx7 I believe) are kinda hard to find in good condition. An FB (81' to 85') is still a first gen but looks alot better, and has better performance. For $2500 you can usually find a really really nice FB for sale. I have seen them go for that much with only 40,000miles on 'em. It's just you have to look in the right places. But rx7's are as reliable as the owners make them. I have talked to people who have had FB's run for 250,000miles on the stock engine.
