Chrysler introduced the 300 Sport Series in 1962. It was marketed alongside the 300 Letter Series, but with less focus on performance. The Sport Series continued after the Letter Series was discontinued in 1965. The seller has a nice 1970 300 convertible that’s said to be a 1 of 1 due to its color. With 86,000 miles, this stately Mopar is in Winter Garden, Florida (with out-of-state plates) and is available here on eBay where the current bid is $20,600 (reserve unmet). Heads up to “Curvette” for this bigger-than-life tip!

The big Chryslers were redesigned in 1969, so the 1970 editions would largely follow suit. The 300 remained popular, although just 1,071 convertibles were built that year (and none would be fielded in 1971). The seller says this car is especially rare as it’s the only one ever painted in Plymouth Blue although the original owner specified Chrysler Sky Blue when the machine was ordered 56 years ago. A 383 cubic inch V8 was standard, but the owner apparently opted for the 375 hp 440 CI engine with a 4-barrel carburetor.

As the seller says, since this is still a one-owner car with matching numbers, we get the impression that an estate sale may be involved. We’re told the blue paint is original to the car, and it looks quite good, though the offset white top has issues. I’m not sure that I would run it through a car wash with the rear glass being affixed the way it is (leaks?).

This running and driving Chrysler presents well overall. And it comes with a fair amount of documentation, which we hope also includes some reference to the 1 of 1 claim. Even if that’s not the case, the original population of these cars was small, so one of the few still on the road today is rare.






Great write-up, Russ.
Gosh I love these land yachts, and this one looks fairly clean, other than the the dash, which definitely needs addressed. The dash almost looks like it suffers from moisture-related damage, but I am probably wrong about that.
Good luck with the sale.
Dash has certainly been exposed to sumfin – and that shreddy top is probably the reason. Not seeing the value of a 1 of 1 based on wrong paint, and hope the reserve is realistic as this needs some attention.
Nice car, but it’s worth what the bidding is at. I can’t imagine what the reserve would be. The car needs some attention, a new top isn’t cheap. $20k is all it’s worth……………to me.
Crappy ebay description in poor English, no underbody shots, zero seller feedback, a dash that looks more than challenged says a lot about this car. I love these cars, but not seeing it here.

One log sentence of word salad.
I agree on all comments. $20,000.00 is tops. Since for me its missing…. AC,tilt steering, power windows and the clock. I seen 300 with these options and go for $30,000.00 and being a convertible. Also I notice that’s a odd looking radio. If someone knows about it please tell me. I watch the start up video and it starts great but its loud. Since no shots from underneath can’t tell if its dual exhaust or shot muffler. Wish we saw the fender tag. Who ever get this i would install the aftermarket AC system which would be easy to install. Lots of room!! Good luck to the next owner . 🇺🇸🐻
That radio is normally *under* the dash, not *in* it. It is an aftermarket FM (Ranger brand?) Multiplex converter with an 8 track. The idea is to keep the factory AM radio in dash, add this below and route the original antenna lead to this unit, then a jumper antenna lead to the AM. I thought you needed the AM radio to be tuned to 1400 (?) and this unit would transmit through the original speakers when powered on. Maybe this is set up different.
Is that a 4 speed with console??
No, you can see a clear picture of the automatic shifter and brake pedal in picture #12 in the ad.

Yep, good eye Steve!
Not true 1 of 1 . I owned an identical 1970 300 with 383/2bbl. Ton of rust by the time I got it @2007. The only difference is engine compared to this car. Bought it from best friend dad who bought it used in late 70’s. Sold it $1200 2008 damn rust! $20k is a lot for this car even as fun as it to drive.
Cars like this suffer from “competitive comparison” all the time. Anyone can go find a “go to the car show today” version in much better shape for this kind of money, or maybe even a lot less nowadays.
Here’s the deal “one owner / matching numbers /original paint ” type of attributes touted in the sales sheet. Nobody cares at this level.
Quite obviously, if you buy a “one owner car”, you are now the second owner. So that false value attribute is now gone, at the buyers expense.
Are you gonna go to a car show and say “This used to be a one-owner car!” Yeah, so was everything else.
Matching numbers might matter with million dollar hemi ‘cudas and Shelbys. Buyers in this price range want an engine that runs well and already looks good.
Original paint, original patina? Yeah, ok. When you look closely at vehicles being marketed in this way, things usually getting unpleasant rather quickly. I’d keep the hood closed at the car show on this one, and the interior looks like it needs to be scrubbed down twice with Clorox before the wife will ride in it.
really cool ride here. you don’t see these monsters on the road too often
1970 Chrysler 300’s came standard equipment with a 350hp 440 with blue engine paint, single exhaust and single snorkel air cleaner. Dual exhaust was optional. Also optional was the high performance 440 TNT with 375hp, higher lift/duration camshaft, larger 750cfm Carter AVS carburetor, swept exhaust manifolds, dual exhaust, and dual snorkel air cleaner. These engines were painted orange. Kind of funny looking at other comments on Mopars, with people complaining about “horrible” sounding starters, they just must not realize that Chrysler starters are gear reduction driven, which of course increases tourqe applied to the ring gear. Really great engineering, listen to a WW 2 or later reciprocating radial engine start, like say a Pratt&Whitney R2800, you will hear the starter spooling up first, then engaging the gear reduction drive to the crankshaft. Awesome sound I think!
I guess you guys get better and more pictures on a computer. I can only view on my phone. The dash that everyone is talking about I have only one picture and it doesn’t show very much. Its dark, can’t see the radio(s) or lack of a/c outlets, but I can see it looks a little “weathered.”
I love these Chryslers. Mopar hit it out of the park several times. The “forward look” of the 50s, the 60s were sexy and the early 70s were huge and stunning.
Had a friend in 1970 who had one of these. Gold, white top, white interior, fully loaded with every option. I would have given my right arm to own that car.
Recently was listed on FB Marketplace for $3500 in Titusville, FL. Showed sold in a matter of a few hours. Now, it pops up for sale again…….🤔

In 1970 the only engine available for the 300 was the 440 TNT not the 383
You’re correct that the 383 wasn’t available in the 1970 Chrysler 300, but the 440 TNT was optional, not standard. You’re forgetting the standard engine, which was the same base 440 4 barrel that was also standard in the New Yorker and Imperial models.
The paint situation on this car is indeed rather curious. Chrysler didn’t offer a “sky blue” (typically a non-metallic light blue) that the original owner supposedly wanted in 1970. It’s possible that they intended for the car to be painted EB3 Bahama Blue Metallic, the lightest blue available on this car for ’70, and this car definitely isn’t EB3. It appears to be EB5, a medium blue that Plymouth called Blue Fire Metallic and Dodge called Bright Blue Metallic, but wasn’t normally available on Chryslers.
Wrong air cleaner so I’ll pass……..
Warning: 2 parking spaces may be required.
Yep; one for the car, and the other directly behind it for the aux gas tank on a trailer!
