Yours looks pretty cool too. And you made it yourself? Did you customize and paint a stock model, or did it come as a kit?
Yeah, made it myself. I like plastic models as others on this site do also. There are a few companies that make the '72-'74 stle cars but the one I liked most was the Japanese company ARII as the doors and hood open, although the interior and engine is lacking.
I added rims from a '70 Road Runner kit, tires from some sort of toy that you take apart from a drug store, seatbelts...
There are some '70 kits available, possible some at Walmart but I think they are phasing them out. Maisto has a diescast metal 1/24 scale Challenger, hard top and convertible that sells for less than $10 but I haven't seen any lately. You can paint it up to look like you car although they are shaker cars. Johnny Lightning has a nice '70 Challenger, some with Cragar S/S, and may be found at Walmart also. This one is the T/A style, they did have the Rally hood before.
