Back to the Future question

Marty wakes up at the end and finds his parents cool, and his mother asks him about his big date. He says he can’t go, and says something about the car being wrecked. Much reaction from the family, and the door is opened to reveal Biff detailing a BMW. What car was Marty talking about?

I believe he was talking about his Dad’s car. Biff had originally crashed Dad’s car while driving(and actually drinking a beer as well). He was made because Marty’s Dad didn’t tell him about “that blind spot”.

So he was talking about the original car he knew about in his original timeline.

I thought Marty’s ride was a truck.

I remember that now. Thanks!

That was in the revised timeline.
ETA: Original timeline-car(brand/model not mentioned) wrecked from Biff driving.
Revised timeline- Biff is detailing the family BMW, Marty’s truck in garage.

You see the wrecked car when Marty comes home the first time, when we first encounter Biff and the McFly fam.

I guess it makes a good gag, but why would you want Biff detailing your car? Is he going to do a good job?

To make it short, being punched out by George broke Biff’s “power” over others. Instead of bullying his way to being George’s boss, he wound up starting a detailing business and being at the mercy of others.

Yes, though there is some jerk left in him. Old Biff in 2015 is the older version of “car detailing” Biff from the second 1985 and he is the same evil jerk we all remember.

Back when there was only one movie, I actually though Biff was partially redeemed at the end. I saw the “to be continued” at the end, but figured Biff wasn’t going to be a part of that.

I know, but part of the trope is that “the ultimate winner is the talented one.” The bully is presumed to have nothing on the ball but intimidation. So he’ll still probably do a bad job of car detailing. So why not hire someone better?

Since it’s his only income, I would assume he has to do good work to survive.

Considering how specific the intrepid reporters of Hill Valley can get, he’s probably afraid of a front page headline like “Local Car Detailer Falls Short”

Local Car Detailer Wanted By Police, Makes Clean Getaway After Short Chase.

Even 1985 Revised Biff was still capable of being a jerk. He tried to get away with just putting on one coat of wax on George’s car, instead of two.

Biff was right. (Likely for the wrong reasons, though)

What Happens When You Layer Wax?

So what actually happens when you put another coat of wax on top of the existing layer. Well, most of the wax you apply will actually be removed when you buff it off.

Wax doesn’t really stick well to itself. So when you apply it on top of a layer of wax, it’ll most likely be removed when it comes time to buffing. This isn’t always the case, it really depends on what wax you’re using.

Some waxes will stick better than others. But generally, the wax is designed to bond to your paint and cure. It’s not designed to stick to more wax.

The best waxes for layering are natural carnauba waxes , which are often used on show cars. They’re not very durable, but do offer a nice warm shine.

LOCAL CAR DETAILER not so COMMITTED to his work

The triumph of Good or Evil, Biff the bully becomes subservient to Marty’s Dad.
