I found a gold LX450 sitting on the side of this mom and pop dealership on my way home from work this past Friday. I went back and checked it out because I have always wanted to tryout an 80's series. It has 228,000 miles on it and drives pretty good. The owner let me take it for a few hours, so I ended up taking it to a Lexus dealership that was over by this car lot and the master mechanic looked it over for me and told the frame is in good condition and for its age and being a southern state vehicle it's in pretty decent shape. He mentioned to me stuff had been replaced and it does need some work done on it to bring it up to speed. The owner of this car lot is selling this car for his brother who is in med school. I actually talked to his brother after I drove the car. He doe not want to sell this LX450 for any less than $6,500, but Kelly Blue Book show the value of the vehicle at around $4,300 with the mileage it has on it. Are these vehicles in such demand, that it's worth what this guy is asking or should I stick to the KBB value?
