The difference I see is that you’ve owned your car almost since it was new. You know the maintenance record and how the car was treated for the last 13 odd years. The OP is considering buying this car now so it has an unknown history for the last 13 years (at least) and untold number of prior owners in that period. Also, the people interested in Supras might not be as kind to that automobile as the people who lust after a Lexus LS400. In other words, it’s more of a “sports” car than the Lexus and was more likely to be treated as such. Apples/Oranges IMHO.
