the MKII is pretty safe
I'll tell you a story about crashes and MR2's. Sit down and gather round' children.
One of my best friends owned both an 1992 MR2 and a 1997 Nissan Altima. I remember when he bought the Altima, the dealership guy was hyping up everything in order to get my friend to buy the car. He even went so far as to point out that the Altima had "three liquid filled engine mounts". I remember thinking, "my God! Who cares? That's one of those details that won't make a damn bit of difference one way or another." My friend bought the car and the salesman went home happy.
A few months later, my friend is barreling down a 4 lane road waaaay too fast and decided to go into the on-coming traffic lane in order to avoid a Civic that was about to run into him. He avoided that accident, but at that exact moment, a truck in the inner most lane went to turn into a cul de sac and broadsided my friend. He was going at least 100 mph or faster. He ended up hopping a curb and SMASHING THROUGH A TREE. You know those trees that usually line the sides of residential roads? I think this one was a maple tree, probably a good 15-20 years old. I would never have believed it unless I saw the broken tree with my own eyes. I went to the scene of the accident. I could just barely tough my hands together when I wrapped my arms around the tree. That should give you an idea of it's diameter. The tree ended up breaking in two and the upper half landed on top of the Altima, crushing the roof in. The Altima continued to barrel forward, using the lower half of the tree as a ramp, and smashed into a chain-link fence. It acted as a goalie net, brining the car to a stop. Miraculously, one passenger was minorly injured and everyone walked away just fine, even the truck driver. Let's hear it for Nissan safety.
All right, now if you're still with me on this one, here's the MR2 part of the story. This same friend of mine goes and buys a 1992 NA MR2. His insurance covered the entirety of his last accident, although he did get his license suspended for it. He drove the MR2 for about a year until engine problems grounded it for a bit. After he got up the cash to fix the engine main seals, it ran stronger than ever (well, as strong as a 5S-FE can, heh). The day that he got his car up and running again, he took a friend for a spin through a residential neighborhood. His rear tires were so bad they were showing threads. We joked about them being "organic slicks". He ended up drifting around a long sweeping 90 bend at about 70 mph. About 20 ft past the apex of the turn, an SUV turned the corner going about 5-10 mph. My friend went to ease off the gas, but his throttle cable stuck. This confused him and he didn't have time to act and he ended up smashing into the SUV. The SUV came to a dead stop and then flew back an extra 10 feet. The driver of the SUV had slammed on the brakes, so a nice big fat skid mark illustrated just how far the car had flown back. It was like a cue ball striking another ball with backspin. The whole front end of the MR2 was just smashed like an accordian. The hood crumpled into the front windshield, shattering it, and the fenders stabbed into doors, locking them in place. The font bumper folded into a perfect v-shape so that each fog light faced the other perfectly, with about 2 feet in-between the two. The SUV's metal bumper sliced into the front wheel, popping it. All in all, everybody walked away from that accident with either minor or no injuries.
Yes, I'm convinced my buddy has what amounts to as a Delta Force squad of guardian angles looking after him.
Even though there's not an engine to protect you in an MR2, the whole entire front end acts like a crumple zone. We examined the deceased MR2 after Horrific Crash #2 and found that the frame rails were perfectly visible, but intact and relatively straight.
I went back and examined the Nissan Altima's carcass back at the junkyard when we went to take out the stereo equipment and the exhaust. The crash had broken 2 out of the 3 motor mounts. The insurance company said that had that 3rd mount gone, the engine may have sliced into the passenger compartment and killed my friend.
So, 3 motor mounts = ability to break a thick trunked tree in half at 100+ mph.
Rear-engine MR2 = big, fat crumple zone that cushions the blow of a 4000 lb. SUV
Does that help answer your question?
