I bought mine new expecting it to be my daily driver and used it that way for ~3 years. I had a relatively brutal 5x65 mile round trip commute - up and down the southeast expressway (The Big Dig) - and put ~70K miles on the car while I did that. This was in all weather: sun, rain, snow (w/snow tires).
I've had zero problems with the car as a commuter - very reliable. It is my "turbo decompression vehicle" - a great way to relieve the stress of the day so I'm human when I get home.
For the last ~2years I've retired it from that rat race; today the car has >80K and I've been putting about 5K on a year. This year I took it down the NASSM in Asheville NC (from Boston,MA) with a group of folks and put about half of this year's 5K on in a single long weekend. Still very dependable.
Only problems I ever had with it were related to bad electrical connections in the sensors added when I had the GMPP installed.
Every car is going to be different, much depends on how well it was taken care of and how well you take care of it. I expect to be enjoying mine for many years.
