How often have you driven in the last 5 years?

Is it in an attached or unattached garage?

Resorted cars need maintenance even if you are not driving them. Especially in rust belt.

They didn’t make a Rallye Challenger in 1971. It would have been an R/T or regular Challenger (w/optional 383HP or 340HP).

But everything on your car could be factory ordered except for the deck lid spoiler. I realize the bumpers aren’t OE elastromertic’s, but what they represent you could get. And I believe that was listed in the 71’Hustle Stuff performance accessories catalog. I know someone that bought his 71 RT Challenger in 1973 and it had that spoiler on it. He claims it was factory. But I bet the first owner added it early in ownership or had them add it at the dealer.
