from my personal experience its almost impossible to find a total "jenian" (Genuine) car that has been in use for 10 years. I was looking for one last year until i found my beauty, with the amount of money i have spent on it (mainly aftermarket mods) people say i could have bought a newer car which would be better blah blah .. but if i was out in the market looking for one and found a good ride i would go for a 99-00 again hands down. The price that the uncle is asking for is a bit on the high side and couldnt possibly be firm, so its up to you to go out and negotiate with him with what you have and see if you can make a deal. Remember its your money and if you like that car and have the money to spend on it then dont let the car just slip by because someone on pw said its not a good deal. my suggestion is talk to him, you can be be the best judge of teh price of teh car since you have seen it and its impossible for anyone to judge the car or its worth without looking at it first.
As i have mentioned teh asking price is a bit on the high side but im sure the notiation room would be larger as well, so go out and talk to him.
