the engine is probably going to be fine, I'd suspect it might need some suspension work and I'd be weary of the brakes if they haven't been done yet. Front endlinks commonly go at that mileage, so check for knocking noise over bumps on the front end. It might be due for a fuel filter change, and transmission fluid change, I'd ask for evidence of that being done before the sale or insist that they be done. I think she'll be tickled pink with the increase in fuel economy though, good choice for that. |
