Congrats on the new ride JC! I really can't say anything bad about Nissan, as I've enjoyed two of their cars in the past (92' Sentra SE-R & 01' Maxima SE loaded). The SE-R will always be one of my all-time favorite cars. In my opinion, Nissan makes one of the greatest v6 engines on the planet. My folks have a 04' Quest minivan and love it. Some minor things here and there, related to Nissan's financial troubles starting in 02' through 05' (cheaped out on some parts). But, nothing major.
I remember when I decided to replace my Maxima with my former LS400. The Maxima was on a lease, and the value had fallen through the floor (they came out with the 3.5 engine in 02', right after I got my 01'). The residual purchase price was too high for my tastes, they wouldn't negotiate, so I turned it in and got the LS. I remember sitting in the driveway looking at both cars, wondering if I was making a mistake by getting rid of the Maxima. I loved it. It was a hoot to drive, and would scream like a bat out of hell (with 220 hp, can't imagine 265). The only thing I would caution you over with yours, is go find an empty parking lot and learn it's limits. Don't push it until you do. Nissan's handle great, but you get no warning when you're about to go over the line, and no real chance of recovery when you do. They're front wheel drive with heavy tails, when they go, you're along for the ride. I almost learned that the hard way in mine (got very lucky nobody was around). And watchout for the torque steer, goose it too hard while turning, and it can be so severe that it takes both hands to keep the car going in the direction you want it to go. That's front wheel drive with over 200hp for ya', but Nissan's are known to suffer from it pretty badly.
They don't ride like a Toyota, but nothing really does. Toyotas have a very unique ride, as does Nissan. It's all in the personal prefference. I made the mistake of replacing my oem tires when they wore out for cheapo Khumos about 7,000 before turning it back in. If you like a quiet smooth ride, don't skim on the tires. Not nearly as much sound insulation in the Nissan brand as there is in the Toyota, so tires are more important.
Have fun with it man! It's a beauty! And stick around here, you've got a lot of knowledge now to pass along to the newbies! We won't revoke your front door key (they didn't revoke mine for the 2 years I was Lexusless)
