Bought a used cozy from our local Facebook trade site $5.00. It was in pretty good shape so I didn't have to do much prep work.

Taking the coupe apart is super simple.
Four screws hold the B pillars and roof together, two at the base where the pillar meets the main body and two at the top where the roof and the pillar meet.
Once the screws are removed just pull the roof forward this will pop the A pillars from the main body.
Removing the wheels can be a little tricky. The red plastic caps on the wheel studs house a metal holder slide a flat blade screw driver under the cap and start prying the cap off slowly and carefully as to not break the fragile plastic, you'll have to go from one side of the cap to the other "wiggling" it off.

The rear wheels can come off one of two ways, the first is brute force pulling the axle rod from the body. The second way is harder but makes reassembly much easier.

Start with removing the red plastic cover, exposing the same small plastic and metal retaining clip as on the front wheels. Repeat the wiggle to remove. Slide the plastic wheel off the rod then tap the metal axle rod though the body and holder.

Step 1: Paint

You'll want to wash the plastic pieces before you start to any real work. I used dawn fish soap and the garden hose to clean mine.

After going to every store in town, aka Walmart and Home Depot I had to settle on a silver paint not the stainless steel I was looking for. One can was enough to cover the entire plastic car.
I used some dark hammered metal look paint I had left over from another project to spray the very bottom of the time machine.

Step 2: "time Circuit"

Having a small budget and this being for my kids, I opted not to over complicate this part. Taking apart a old alarm clock to be placed in the dash. Placing the screen face down on the dash trace around the face of the clock. I used a dremal to cut the hole. Then feed the clock the hole putting a small amount of glue on the edges before setting the face in it's new home using the hole for the steering wheel I could put my finger inside and move the face of the clock into place.

Step 3: The Look

Being on a budget I used as much scrape as I could. The box on the front corner is a USB housing from an old dell computer, two screws that once held it to the case now hold it to the time machine. I used vacuum hose I had here for the side "wiring" a small piece of PVC tubing painted with the hammered paint, speckled with sliver. White zip tie hold downs screwed to the body keep everything in place.
As for the other side I didn't have another box so I used a tee fitting from an old nitrous set up and blue vacuum lines routed and mounted in the same fashion.

Now we needed what every time machine needs a flux capacitor. A trip to the hardware store got us an electrical outlet housing and solid faceplate. Using a marker to draw the hole and a dremal to cut it out. Side note the dremal heavy duty cutoff wheels are a joke, I went though eight of them cutting a small hole.

I used vacuum line cut down the middle to run around the edging.

I had to put lights on this thing, to mimic the lighting effect of the time machine traveling though time, resembling my budget and having a prime membership to Amazon I found a 16' roll of self adhesive LEDs for cheap $7.00. Running the first strip around the front bumper, and the second up the B pillar across the roof and down the other side. All wired to a 12 volt battery mounted between the cooling ducts and the flux capacitor and two switches mounted on the A pillar for easy use by the kids.

The Mr. Fusion I used another piece of left over PVC tubing cut down and epoxied to the roof of the time machine.
The roof also has a small metal box painted to match the other part bolted over the center section of the lights.

I felt the inside was still a little bare I opted to put an old nitrous gauge in the dash by drilling a small hole and using the threads of the the fitting to screw the gauge to the dash, it resembles the heat gauge from BTTF 3 so plus.

Now for the back cooling ducts. I wanted to use sheet metal but at this point the funding for this project was running out. So we decided to use thick cardboard cut and painted with the dark hammered metal paint to match. All held together with wood glue. Then mounted to the back of the time machine.

Step 4: Zing

I've been looking into the the zing laser for a while now, I would love to win this grand prize and be able to start a home base business of laser engraving.
