so i want to buy a 1.3 rotary mazda rx8 from 2005 as my first car. I found a really cheap one ($2800) but it has a broken crankshaft bearing. My question is, is it safe to just press in a new bearing? or is it possible that other engine parts are broken as well? and is 2800 a good price? it has 80k miles on it. any tips on what i should look for when buying it?
