That's unusual, you don't often see modded IS250's. Being sold by a bodyshop / modding outfit, naturally the body work looks to be in tip top condition. Price reflects this though
The MOT history suggests it's been driven enthusiasticaly? (Multiple advisories for worn rear tyres), but on the other hand it looks like it might have a new exhaust section - check if this was repaired or replaced.
The declared mileage is 68K which is in line with where it should be so it's most likely a data entry error at the MOT
