...the price seems a bit steep, but it's also coming from a BMW dealership. I had a good experience with BMW Autohaus, having purchased my '02 M3 there. Take a look through Autotrader and equivalent to see comparisons. You can probably pay about $10k less for an equivalent kms car that's likely a bit older, and have that money aside for potential repairs, if you're also considering warranty.
All M-car engines do eat oil-- approx. 1L per 5-10,000kms, so nothing special there, though a bit surprising they would have it like that to show.
The E9x cars are pretty solid, so nothing particular to look for that I know of.
Good luck on your search.
Thanks, I am only looking for a E90 as I just like how it looks.
