I got mine from Vision Fine Car's on 400 and Steels (I think). The car was cheap, but they were horrible with customer service.

But since I'm a little more mechanically inclined than the average person, I was able to spot some defects that were fixed after much hassle.

 

I got mine in September last year from Dixie - 401 Infiniti. I had to play hardball with the price but I think I got a decent deal. About $1000 more than I wanted to pay. I've put 12,000 km on the car since and no real problems - just rear brakes and it seems like my alignment may be going (or it could just be the crumby RSA tires which have little life on them - not sure). Right after I paid for the car and had it off the lot I noticed a crack in the rear taillight (backup light portion) and they fixed it no questions asked. I also had them do some paint work on the bumper to repair some scratches as part of the deal and pull a couple minor door dings. Seems the bodyshop they used is not the best as the paint on the bumper crazed and it needed to go in again to be repainted - no issues though from the dealer and they paid for a rental while the work was being done (a KIA Forte - drove like crap). The dealer also did a complete service on the car before handing it off. One thing was the cargo nets were missing and I never got new ones which one of the sales people promised. Overall though very happy with the car, it was a service loaner and had 24,000 km on it at the time. I got it for $31,000 plus PST\GST, I think I did OK.

 

What about Alta Infiniti? Check them out sometimes they got good stuff, Not sure on the prices though.
Personally I got mine used from a private deal a few years back. 35000$ for 25k kms on a g35 coupe 6mt guy was leaving the country.

 

btw i got mine in 2008 around may from the lexus-toyota dealer, 2003 65k for 21,900 +tax. i dunno seemed reasonable to me that time

well mine is at 89K right now cant believe i have done 24k on it, i think i have paid around (i probably spend around 2k in repairs on it so far and it includes 5-6 oil change, compression rod, rear bushing, battery and filters)

the previous owner was a single professor at uft and seemed careful. well if im gonna sell my g its should be this year cause after this the salvage value goes down faster, however if i sell i have to spend at least 10-15k to actually get a newer and a comparable performance car. thats why im gonna continue keeping my G as long as i can till i have enough to get the new 3 series cheaper

 

Got mine from a private seller. It's been over a year, and generally speaking I am happy. The car has the valve cover leak which for me isn't a big issue... I'll replace it myself when the time comes; it's a very common problem and I would of had it done under warranty if I got my car 2-3 weeks earlier... sucks but what can you do. Up until now I haven't done anything except regular maintainance.

When I was searching, all the cars at private dealers were sketchy. The only good ones were those at Infiniti/Nissan dealers; I would prefer to buy from them but I would be spending a few grand more and that was an issue for me.

 

Bought mine from an infiniti dealer in '06. Picked up a '03.5 IP on black with nav and 6mt of course. That is a hard combo to find I must say.

 

I got mine from Volvo dealership. The manager there used to own my G35 and used to work for infiniti, but since he moved to volvo he had to switch it...

 

Got my current G through Lease Busters.
You have to watch, but there can be some great deals when some people HAVE to bail on a lease.

 

Alta Infinti in 05.

Bought it with 67 000kms. Currently just a tad bit over 100 000kms.
