What's the ole' saying......"if it's too good to be...." OR even back in the days when they spoke Latin ---"Caveat Emptor"
Just be careful and have someone (3rd party) check the vehicle out. If you are asking....already makes me think you are skeptical. That's a good thing when purchasing something with this much coin. I would think 190 miles would be flawless....'exteriorly' and 'interiorly' (if that's a word).
Or, it could be the hardest 190 miles ever put on joyrides at the dealer by the dealer's son (or daughter) or top salesman. (Trust me on this statement).
Guess I'm paranoid in my old age---summary---get it checked out....Best of luck, sounds like "Mr. Depreciation" is on your side and you are coastin' downhill in 6th passing corvettes left and right my friend
Post some pics if you end up pulling the trigger on it.....
