I have a little 2.5 that just rolled 200K, it still runs like a swiss watch. Depending on the location in Texas you could be by the sea, which could cause some salt corrosion, etc. But, if you like the pictures, and this is a one owner car, check the service records and decide based on that. Your commute is like mine, hell - I could (and should) walk or bike to work, so if that's a problem you can always turf it for awhile
The 600 mile round trip I'd do once a week in mine right now if necessary and never worry for a moment.
Just my .02
