No doubt RX-7's are beautiful car and perform well. But they can by pricey to work on due to them being a wankel rotary. Also unless you know alot about rotary engines they can be a little tricky to work on. RX-7's also have an overheating problem due to thier design. But in the end it's your choice, but you picked the wrong place to ask the question rx-7 or Z. I say Z all the way!!!
