When you start out your sentence stating you had a "myriad of issues" and then say the same thing three times; "overheating", you kinda put your foot in your mouth. It sounds like you had someone work on it three times and not fix it right the first time. Sure I've had to drop a little bit of money in my LS to keep it going well, but there are a couple of things I need to point out, 1) it's a luxury car, and has a lot of bells and whistles that at some point may need to be fixed or replaced, this isn't a problem with the car per-se, just the fact that it has more "stuff" than a normal econo-box has (DCCV, heated/cooled seats, high-end audio (for it's time), etc...) I have owned an Infiniti Q45 and once it hit 80K miles it started falling apart, took a whole bunch of money to get it right again, and then lasted for another 80K without much fuss before the tranny died. This car has over 170k on it (I bought it at 150K, and have all maintenance records), other than changing the normal stuff out (plugs/cops, cats (due to bad cops) and vcg's, along with some suspension bushings and tie rod ends) it has been trouble-free. If I were to write a pros/cons list of owning this car, I would have far more pros than cons.
For instance, I love the way it looks (ever since they came out I wanted one). I love the way it drives, the comfort level inside, the sound quality is great (I have the THX), plenty of power for me, and I just feel good driving it. Knowing that I got such a good deal on this car (I paid less than 6000) and that I have more features than most brand new cars 4x the cost also helps, not to mention the timeless style.
All in all, it's been a great investment for me, it's not a Honda Civic or Ford Focus, but it wasn't meant to be. And in the end, if you enjoy your car and you take pride in it, that's all that really matters.
