I'm leary of any car ads without pics. 150k is pushing the boundaries of "usedness" imo but toyotas are certainly strong. Thats a lot of miles if its primarily city driving but if she teaches in Miami and had to drive 400-500 highway miles a week then thats a different story. Seller says there was a recent tune-up but you should definitely find out what has been replaced since she's owned it and how many miles are on those parts.
