One truck, Two Truck, White Truck, Red Truck

Some of you have been wondering about our vehicle situation.

About 3 weeks ago Josh's work truck broke down. It is so old and needs so much work, we really felt like we shouldn't fix it, but to begin a search for a new one. But wait, we can't really afford a new truck....but wait, God does this mean it is time for us to jump into the business and trust fully in you??
After a 6 hour day in the car, searching every dealership from here to Massilon we found 1(the white one). We weren't really interested, it seemed to over priced and when running it was idling really funny. We passed and had no luck the rest of the day. We did find a dealership who had just sold the exact truck with all the features we wanted, the night before for under the limit we set for ourselves. UGH!
Josh wants a Ford F250 XLT v8 5.4 L crew cab, long bed and 4x4, this is a VERY hard to find truck. Since we were at a loss and couldn't find a truck like this anywhere we went back to the White one. We couldn't get financed (our credit is getting better, but not good enough). My mom decided to co sign for us (Thanks a bunch). Last Saturday my mom picked us up and we headed to sign all the papers, my mom left with the he kids, Josh and I took the truck out for a last test drive (they said they fixed the idle problem) and all the idling problems were still there. We felt a big NO, we couldn't buy a truck like this there was obviously something wrong, and with NO warranty, we weren't taking chances ( you all know what happened with the Jeep...blown engine after 3 months..we are VERY cautious now). We call my mom to come pick us back up. The salesman says he will send it to Ford to get it checked out. Just yesterday he calls to tell us it was fixed, it was a coil cover...something like that..the spark plug for one of the cylinders wasn't working...even though they just replaced it. Nice huh??
Soooo in he meantime this guy Ray calls us, Josh had test driven this truck, before his truck dies..just because he wanted to=) The truck is still available(this is the red one). Hmmmm, so we go test drive it again. It is newer, nicer and lots more options than the white one, but more miles. We really like it, we really like the sales guy, is this too good to be true?? Oh yeah and it is the same price!!
My mom's credit will be checked again through this dealership (same bank) so hopefully we will have a truck SOON.

Finally
The object of this post...
We want to stay in God's will, if He wants us to get the white truck we will, but we would rather have the red one=) But we want the best one, the one that will last. The one GOD has for us.
Please PRAY for us. Thanks.
