I've talked about how it shares parts with my brother's Camry, which is just about to roll over to 200K miles. But this was with the dealer owner's nephew. It sounds like they're trying to get rid of it, and the lady who is selling it has been a long-time customer there... Probably why they have her car on the corner of the lot.
Per the sludge issue:
Given that its a 5S-FE and I always change my oil at 3,000-3,500 miles (I use Valvoline MaxLife), it shouldn't be a problem. Its a tough little four pot, and with only 77K on the clock, I'm really not expecting any issues until roughly 120K, or about the time I'm going to sell it. I figure by then it'll likely start needing work, and it would be a good time to move on to a new car... Either way, with the way I drive, I won't hit 100K for a little over two years.

Either way, I'm flexible. I would love to have a car right now, I'll admit that I'm getting a bit desperate, but I don't need one until the end of the summer. I'll stay firm that $7000 is the target, but I may concede and do $7250 or something. I see that NADA and KBB are meeting up around $7500, but Edmunds has it priced as low as $6600 even when in excellent condition. Seems like that's the magic area... $6800-7500.
