should i drive or get it shipped 33hr drive

I have driven two different '96 900 to Minnesota from Vermont—1,000 miles—in frigid winter temps and mid summer. I usually do it twice a year and I have never had a problem other than a flat and flooding it at -20. One car had 200,000 miles on it and I paid $300 for. I've been doing it for 6-7 years and the only times I needed a tow where 4 miles from home, a pulley and the ignition. Both, I should have fixed earlier.

I think that if it is going to break down it isn't because of the length of the trip. And the type of failures aren't going to be found by a tune-up. Assuming your car is an average car.
If you are really worried, look into getting AAA and one of their packages that offers lengthy tows.
Think of it as an adventure. If it was me, I'd drive it for you for return transportation costs plus one or two nights at Motel 6 and $300. Problem with flights though is they are more expensive to buy tix at short notice. So that is the same as the cost of transporting it.
If you have someone do it, you should be able to get info from their insurance company—given approval—and maybe work references and the like.

The other option would be to sell it and buy a car where you are. Might come out ahead if you figure in the $800.

You should drive it. There are worse things than being stranded by the side of the road.

I'd offer to do it but Texas isn't a place I'm interested in traveling to in the summer.

Come on drive it. Beats a tour overseas.

When it comes down to it, you need to decide on cost vs. mileage/hassle. I have done both options with my low mileage ng900. I will go through my experiences with both options to give you some insight into what each entails.

Driving: me and my dad drove my then 20,000 mile ng900 up from Daytona Beach FL up to Greenwich CT in 2004 and had no real problems apart from a small oil leak that developed for some unknown reason. It was about 1,200 miles and was not too bad because we split the driving into 2 stretches by staying a night at the worlds worst Holiday Inn. That said, I thought the trip wasn't unbearable but it is not 2,000+ miles.

Shipping the Car: I recently moved to California and there was no way I would ever drive the 3,200 miles. I got my car shipped in the front position of an enclosed car transporter and cost roughly $2.5k and my car arrived a complete mess with damage on the paint and wheels. An open trailer would have cost a thousand but you are still exposing your car to 2,000 miles of grime and other nasties on the road. I was not happy as it was a professional and reputable car agency I used.

I would most likely prefer using a transporter because I frankly do not trust my car to take me any appreciable distance without breaking down but it also costs a nice chunk of change so that is a consideration. You also get more of an experience with a road trip and the car was meant to be driven!
