New rx8 owner

Well until two days ago I didn't know anything about rotary engines or how they differ from other cars. So I went to a Mazda dealership that had only one 2004 rx8 6 speed manual with 130,000 they also had it over priced, after the test drive which it drove fine I wasn't really use to the rpm , got back they tried to move it and turn it over for five seconds started, then they got a battery box and it started up, took it to the back to get it looked at. I almost guessed something simple like the battery at first, after asking multiple times will it make it back to where I live and got a repeated yes, made an offer that was under a fair price that I could use towards fixing it. Car was still in back, they did take their time , then came back offered it to me for about half the asking price said it would need some work later on but after asking again will it drive to where I live and them telling me yes, I got it. :banghead: well it drove fine for an hour until I noticed a light flashing " low coolant " , then hit traffic jam started idling low almost died a few , about thirty minutes form where I was going dash lights started coming on, then I noticed gas gauge was empty and light was on " best guess heat messed up electronics" fuel was still there, made it back and tried to turn it over didn't do anything. The sales guy called the next day I told him about 8 pm, followed by the coo/manager of the dealership sending me a email at 2 am today I told him what happened and gave the number to the shop I left it at. Anyway very interesting start, hopefully things work out.
