while listing to car talk I would say that some non american cars are just as bad, that allways make fun of VW's burning oil. I have also heard of toyota's 2.7 lt inline 4 engine blowing at 70kmiles due to flawed oil passages clogging up. My friends honda was a nightmare to work on and the parts where soo expensive not to mention it being rusted out, so IMHO All of the car makers have some crap models/ motors,/ bad days.
My personal experance had been as follows,
1988 chevy s-10, body is heavy rusted and I have owned it for 11 years at 124kmiles when I got it, nothing magor and it has 181kmiles, orginal 2.8 guttless motor and orginal transmition. (My dad owned it and it was unreliable when new, a workmanship defect was found and fixed)
1998 jeep grand cherokee, rebuilt front axle at 90kmiles, cracked exhust manifold at 150kmiles and currently has 164kmiles. I bought it 4 years ago it had 52kmiles. I dive off road and into deep water at times so both failers where probly my fault.
2001 buick regal gs 22kmiles , just got it, so no info.
So if your minivan was taken care of and it's not beat on you may make it, just carry a cell phone just in case. No one thought my S-10 would last as long as it has, I figure I was on borrowed time 11 years ago.
My dad just got a dodge magnum with the hemi so We will see if Chysler cleaned up some of there act.
