OG Magnum Dude here...had an '05 R/T that I modded modestly; SRT suspension swap, Foose staggered wheels/tires, blackout lights/grill, the famous Zoomers exhaust, etc. It was cool AF and I most definitely have a soft spot for them...
The red SRT has a 300 front end, which is how they came equipped in Europe so someone did some work on it at some point, could be accident related so who knows without a CarFax, etc. The Charger and 300 SRTs were definitely the more popular of the 3 original LX SRTs from what I remember. Not sure production number wise but I'd hazard a guess that the Magnum SRT had the lowest overall production.
If I had the cash handy I wouldn't hesitate to pull the trigger on a super clean, all original, low mileage Magnum SRT and I wouldn't do fuck all to it except drive it. It was cool back in the day and just as cool, if not cooler, now.
I get it, wagons are love/hate. I'd likewise LOVE a CTS-V wagon (which are near unobtanium and priced accordingly), or an E-series AMG wagon, and Audi obviously has some sweet wagons too. There's something about a vehicle in that configuration that can just flat haul azz and carry a shit-ton of crap too. Full disclosure a '57 Chevy wagon would be TITS!
