hey Deby...
Sorry to hear about your accident. I'm glad that you made it out with only bruises.
I, too, had a bad rear end accident on the fwy about 15 years ago. I was coming to a slow (about 15 mph) on a long exit lane and some guy, not paying attention to what's in front of him, slams into me going around 65+. I was driving a company station wagon at the time. But, during impact, I swear, it felt like time slowed down. It's funny, because a few seconds before impact, I heard a tire screech and thought, "oh man, someone's going to get hit. And boom! Upon impact my seat back support broke and collapsed backwards flat and I felt my body going through the motions. Glass from the rear window shattered on top of me and my legs kicked up under the dash.
I came out with bruises to my leg and a pulled arm muscle. However, a few days later, my back and neck started to ache and I was instructed to go to a chiropractor to get checked out. Turns out, I ended up seeing him for about 4-5 months.
Point to all this is I suggest getting checked out by a chiropractor or equivalent (if you haven't already) as traumatic accident effects start to appear on the body a few hours or days later.
Glad to hear the Isuzu protected you to the end. Good luck on your quest for another replacement.
