Haha it's not just men and their babies! I myself have an R34 GTR Skyline and an R32 GTS-t, my Husband has a Supra - We're selling the lot! They're just not practical for parenting! Hubby's getting a new Navara and I'm getting a new Turbo Audi Quattro - Much safer, more practical, less of a money pit for me as I won't want to mod it and still has lots of go to be an enjoyable drive - Not to mention a step up in class! Have you thought about maybe getting an R34 4 door or just buying another cheap little family car and keeping the R34 Coupe as well? Sorry, prob not the answer you were looking for... I'm not sure of any car seat that will fit, not to mention pram that will fit in the boot and all the other things that come with baby...
