i checked on kbb.com
the retail price for excellent condition with that mileage is 14,500
private:
excellent 11,500
good 10,660
i wouldnt say its a GOOD deal, id say its fair. as long as the title is clean and there was no previous damage you arent getting ripped off... but its not a steal. im new to lexus but the mileage doesnt really seem to be an issue with these cars. good luck!
