Re: Grand Cherokee 5.9 Advice
Interesting sentiment.
Approximately 14,000 customers put out over $38k for the 5.9 in '98. To pay
only $7k (less than 20 percent) more some 8 model years later for a
similarly loaded, Hi-po vehicle is really quite a deal.
Of course, those people could all be nuts and may have thrown their money
away. Perhaps we should ask if any of them think they got taken?
Meanwhile, the rest of us should make the Jeep dealer our best friend so
when one of these deranged types brings his/her '98 in as a trade, we can
grab for it $7-8k before it goes to the used car dealer.
