Too good to be true? A red flag?
I do not know your location. And therefore do not know the laws there. The general location could possibly be helpful.
I live in the U.S. and frequent 2 different states with 2 different sets of laws pertaining to vehicles badly damaged in a collision, flood, etcetera, being “repaired” and then resold. One state requires a “rebuilt title” issue which alerts buyers. The other state does not require any changed documentation and therefore no red flag warning.
Many/most “rebuilt” vehicles I see for sale are of the low mileage variety. I believe they are total losses (as labeled by insurance companies) and spend a lot of time sitting while be sold/auctioned and then “repaired,” which attributes to the low mileage (can’t be driven for a length of time).
Long story, even longer, I am always skeptical when seeing an unusually low miles vehicle for sale and check extra carefully for evidence that the car was “rebuilt” prior to coming to market. Be cautious unless you know the car’s history accurately.
