Well, you don't have to remove all of the air handling stuff above the engine to get at the coil packs or spark plugs but it does make it easier.
If you are a person that can work only with your left-hand and you can really visualize what is going on when your back is killing you while you're are bent over the fender (cover so no scratches) up to your armpit, then you too can be a DIY FIT mechanic. There are some tricks to disconnecting the coil pack trigger wire connectors. Let us know if you want to try it.
I do know that the majority of the GE8s had the airbag recall, and some also had the passenger bag air recall. So plan on getting that fixed while its still a free option.
Yes the 151r battery is underpowered and not too many companies make that size so availability may be limited.
One other cosmetic issue. The headlight UV coating deteriorates very quickly. The unique odd shape of the headlights is that they wrap around to the top of the bumper/hood area. Which means long exposure to the sun on the top portions.
I have already had to replace one headlight and due to replace another. My suggestions is every time you wash the car apply some liquid spray on wax. It will help fight the UV rays from eating up the coating.
-A lot of reported A/C issues.
-No problems with the battery and Chicago winters get darn cold.
-Some tranny issues reported. I do fluid changes more often than recommended as the fluid that came out didn't look good when I did it on schedule.
-third clutch transmission pressure sensor is a widespread problem. Fortunately it is relatively easy to replace and not expensive (~$40).
