I agree that putting wine in a refrigerator is fine for SHORT term storage, say, a few months. I have heard that it is not good for wines long term because of the vibration that occurs when the refrigerator cycles, but I must say I have not noticed that. I found a few bottles of white in a lower drawer of the refrigerator in our garage that had been there for several years, with no ill effects whatsoever.
As for reds, you are going to get all kinds of answers regarding rack storage with occasional bursts to 85 degrees. Given, that is not ideal, but if it doesn't push the cork up, or force wine out around the cork, most red wine is hardy enough to take it without noticeable change over the short term. If that kind of swing has an effect, it is not likely to show up for a while. "Short term" and "a while" will depend on the wine. I left a bottle of young inexpensive bordeaux in a garage with that kind of heat swings, and more, for at least a month, and drank it immediately (well, after cooling it down for a day) and it was fine - though I had no reference point for that wine. It certainly did not taste cooked. Neither did an Edmund St. Johns wine I left in my car too long and it got so hot it forced wine out around the cork. So I would think for sterner reds, a few months should not make a noticeable difference. For wines meant to be consumed immediately, it may make more of a difference.
Sorry I can't go further, but the only wines I have experience with that have been exposed to 85 degrees have been accidents, and they are fortunately few.
I guess I would put most things in storage (or in your wine fridge) unless you were planning on drinking within a month or two. The drive is short enough that there is no good reason to gamble.
