I’m really starting to get into the idea of getting one, partly because i love rotary engines and partly because they’re both special and fun to drive (they are seriously rare in germany’s south).
And although i feel like i’ve gathered enough information on what to look for when buying and how to maintain it, i would still like to ask owners for special tips for both buying and maintaining and on the side, what sort of mileage you’d get.
Thank’s in advance, i’d really like to go from fwd greyness to rotary driftyness as soon as possible :D
(depending on the market, you can count the not ruined not to expensive ones round here on one hand)

What possible errors would you look for an an evo XII
If you were trying to find one to buy?
