This is an excellent car--is very reliable, is extremely luxurious and extremely fun to drive. Right now I'm at 131,000 on my 1999 touring model-- this car can easily go another 160-170k without any problems. Maintenance and gas (ALWAYS USE PREMIUM IN YOUR I) can be a bit expensive, but the upkeep is a small price to pay for such an otherwise flawless machine.
This car is as good as they say, no mechanical problems even at 150k. I'm a big guy and the seats do me well. I am comfortable and my back is good even on long trips. This car has it all would buy another in a second.
When I was first looking at different cars, my thought was to get a Toyota Avalon. I test drove the Avalon, and liked it. They wanted a lease that wouldcost $599+ per month. I test drove the Infiniti I30 and liked it. The lease was $399 a month, $399 down. I loved it. Now my lease will be up on June 3rd, and I'm going to buy my car for a residual of $16,500. I like it that much.
