I want to eventually get into racing but need to start with a car that is of the friendlier side to the pocketbook.

I currently have a street legal 944 which I have started setting up for autocross and DE's, but am concerned about the costs of building and maintaining this car. Believe me I love the Porsche brand but I love sportscar racing more and have been on the side lines long enough (just turned 42 today) . Before I go any further with spending money on my 944 I want to explore other options as far as car choice.

I want to stick with RWD. I am also a novice mechanic with limited free time so I want to stick to a car that is fairly easy to work on (I would not call the 944 novice friendly). I grew up around the GM brand (78 Camaro 305, 79 Firebird Formula 301). I'm wondering how a mid 80's- early 90's Camaro/Firebird would compare in cost and fun to a 1st or 2nd gen RX-7. Also other considerations are the Mustang or anyother suggestion.

Thanks for any help.
